Testimony by a Voluntary Evacuee from Fukushima: A Mother Reveals Health Issues She and Her Children Had

Anonymous testimony of a Fukushima single mother made during the December 4, 2013 press conference by the Fukushima Collective Evacuation Trial Team, and transcribed by Kiiko here. It was translated into English with permission of the woman, a voluntary evacuee to Yamanashi, who gave the testimony. She strongly feels stories like hers should be heard by others so that the severe reality faced by some Fukushima residents can be recognized.


Testimony by a mother with two daughters and a grade-school age son who is the youngest.

I was born and raised in Fukushima Prefecture. I was living in Fukushima at the time of Great East Japan Earthquake and the nuclear accident. This summer, I decided to voluntarily evacuate to Yamanashi Prefecture due to health issues experienced by me as well as my children. I would like to describe how I came about deciding to evacuate and how things changed after the evacuation.

At the time of the earthquake and tsunami, the lifeline was disrupted. In order to obtain food and necessary goods, my family walked to a store we would normally drive to. We had to wait in line for hours to shop. The news of the nuclear accident came in the midst of it. I still remember how it was very hard for me and my children to breathe due to strange smell and difficulty taking a breath.

Every day the government and specialists said on TV, "There is no worry." and "There is no immediate health effect." Despite feeling anxious, I took those words as is, and we ate local vegetables and drank tap water.

My children had restrictions on outside activities at school. They could not play outside, and those were difficult days. We were just living a day-to-day life, and I was too busy with work and didn’t have time to  research radiation and radiation exposure. Time went by, and there was a thyroid ultrasound examination as part of Fukushima Health Management Survey one year after the accident. 

When the results came in mail. Two children who were examined both had nodules and were classified as "A2," and "No need for a follow-up until the examination in two years." I was in shock.

There were no ultrasound images, and I had no idea what kind of condition they were in. It was just a piece of paper, and I was full of mistrust.

I thought about evacuating from Fukushima then, but voluntary evacuation was not guaranteed to get financially compensated. As a single mother living with my parents, I had no courage or money to leave home to support my children, so I gave up.

I wanted to get thyroid ultrasound examinations on my own, but I had been told "No local hospital would conduct thyroid examinations." Time simply passed by while my worries continued.

When the new year came, I tried to get my children life insurance policy as I thought "anything could happen from now on." I reported the thyroid ultrasound examination results in the application form, and I was told later on that they were "unable to attach any special policy regarding cancer." I asked for reevaluation and managed to get policies, but this experience made me realize that "The fact that the insurance company came up with such a result is because they decided the (cancer) risk was that high." I was worried and tormented, and this made me begin to collect information regarding radiation and radiation exposure.

Later on I found a hospital that would conduct thyroid ultrasound examination. We all underwent the examination including the daughter who did not qualify for the thyroid examination by Fukushima Health Management Survey, and it turns out we all had thyroid cysts which were recommended to be followed up every 6 months.

I couldn't trust the whole body counter (WBC) examination conducted by Fukushima City or Fukushima Prefecture, we were tested by a non-profit organization. All of us had previous WBC test results below the detectable limit, but two of the children had cesium 137 six months later. I had no idea what to do. I cried every day, hiding from my children.

From that time on, I began to have dry coughs of unknown etiology. When I went to a hospital, I was told "An increasing number of people had the same symptom." As my cough would subside during a convalescent stay outside Fukushima Prefecture, I asked the doctor, "Do you think this is the effect of radiation?" I was simply told, "We have no such reports, so we don't know."

My son in grade school began to complain of bone pain in the sole of his feet. Furthermore, many others around us, at all ages, also complained of bone pain in the soles of their feet.

If we evacuate outside Fukushima Prefecture, can we make a living under such conditions? I was so worried about my children getting used to the new schools and a new life that I was not able to make a decision on evacuation. However, I finally decided when someone told me,"Your health and life take precedence over such little matters." I began to look for a place to evacuate to and eventually settle.

Most of the government-assisted evacuation arrangements had ended at the end of last year. The only option was to rely on a private group making evacuation arrangements. As I wanted to move to the west of Tokyo, we ended up evacuating to Yamanashi Prefecture.

Health of all the family members quickly deteriorated during the period awaiting evacuation. My work had necessitated me to walk around a high-radiation district a lot for several months. My dry cough got so bad to the point of nearly choking in the middle of the night.

Beginning with the soles of my feet, bone pain extended to arms and legs. Parts of arms and legs exposed to air had stingy pain and itchiness. Stuffy throat and phlegm gradually worsened.

There were occasions when a sudden episode of fatigue temporarily immobilized me in a car. The arm bone pain was so bad that I could barely open and close doors. I got so scared that I stopped walking the particular district, and soon the bone pain subsided.

My grade school age son continued to have nausea and headache upon awakening in the morning. When he went to the hospital, they found blood in his urine. His allergies had tripled what he already had. Doctors diagnosed allergies as the potential reason for not feeling well.

However, no medication relieved nausea and headache, and he often had diarrhea. I also began to have continuing nausea, headache and diarrhea.

When we went to a different hospital, we were told the symptoms were psychological, and the etiology remained unknown. At this point, my son's blood pressure had gone down to 82/50.

My son's health gradually deteriorated with the dark circles under his eyes expanding. He could barely go to school during the three months before evacuation.

Air dose level immediately outside the house was 0.8 μSv/h, but there were some spots with air dose level of 1.5-2.0 μSv/h inside the property boundaries. Even inside the house it was 0.3-0.5 μSv/h. That was the condition we lived in.

I discussed with the school principal the thyroid issues in my children and the anxiety I felt about my children walking to school through some areas with high radiation, but all I got back was an unbelievable answer, "I think even 5 mSv annually is fine. You can't live anywhere if you are worked about such matters.

When I checked the air dose levels at school on my own, there were multiple spots that were right around 1.5 μSv/h. However, the school would not release such data.

Then the school swimming pool reopened for swim classes after two years of closure. I was at a loss for word when the release form stated, "Any students who cannot participate in swim classes are required to turn in a medical certificate from a hospital."

My daughter already had a skin ailment of unknown etiology, which got much worse than ever. My son sensed abnormality of his ill health and sometimes would cry in bed asking, "Something like this never happened to me before. Why is it happening now?"

First week after we evacuated to Yamanashi, we had nausea, headaches, diarrhea and fatigue. We also had badly stuffed throat and phlegm. But gradually the frequency of theses symptoms decreased from every two days, every three days, and so on. I could tell the dark circles under my son's eye was gradually lightening up and  disappearing.

Soon after that, my children and I went to a hospital in Tokyo for thyroid examination. We were surprised to hear the results later, as all of us had results which were totally different from the results in Fukushima

My son continued to have blood in urine. We were told to "take him to a specialist as the blood test results are concerning." When I took him to a hospital in Yamanashi, he was diagnosed with "autonomic nervous system disorder."
However, the diagnosis was not convincing enough, considering his symptoms and my own ill health. I came to distrust hospitals, and we quit going to doctors.

About one month after evacuating, my children and I felt much better, and my son was able to go to school.

Although we don't feel well occasionally, we no longer have  abnormal symptoms we used to get in Fukushima. It was only when our health improved that we realized that "we were in a scary place," and recognized how scary radiation could be.

After we evacuated, we returned home to Fukushima twice. Each time our health worsened.

More people who remained in Fukushima are suffering from the same symptoms as mine. More people have died. There are more children who got leukemia, who began to have bloody noses and who have thyroid cancer. Children with thyroid cancer and their mothers are really suffering. Many parents want "at least children" to survive, but parents need to be healthy to be able to raise the children.

I wish both adults and children would be evacuated from high radiation areas as soon as possible.

Many evacuees, including me, are full of regrets that they didn't "evacuate sooner." I don't want any more people to feel the same way, regretting that they "could not fully protect the children."

I would like the government and TEPCO to reveal the truth and own up their responsibilities and do what they need to do.

In addition, they should get to know more about how we are burdened with double and triple suffering due to radiation even before our psychological damages are healed.
Thank you for listening.

From the Q/A session:

Question: You said the thyroid examination results in Tokyo were different from those in Fukushima. How so?

Answer: In Fukushima, my son's thyroid ultrasound examination showed two cysts. When we went to another clinic, it still showed two cysts. When I took him to a hospital in Tokyo, he had not only cysts but also nodules; he was given a diagnosis of thyroid adenomatous goiter. In addition, he had lymphadenopathy with over 10 lymph nodes involved.

Implementation status of the "thyroid examination" in Fukushima Health Management Survey

1   Progress status and summary of the results

   (1) The primary examination
   The Fiscal Year 2013 examinations have been conducted, in approximately 158,000 participants from 34 municipalities, since April 22, 2013. In addition, participants from the previously targeted municipalities who have not been examined were encouraged to participate in the following ways: Letters have been sent to them, explaining the examination implementation outside Fukushima Prefecture or in other municipalities; and information about the examination has also been available on the website. As a result, more participants have been examined even after the end of the target year for their municipalities, and 82.4% of overall participants have been examined. ※1
   Moreover, thyroid examinations have been conducted in facilities outside Fukushima Prefecture since November 1, 2012. ※2
   Also, 94.5% of the 238,785 participants had their examination results confirmed and had them mailed. ※3,4

Progress status (as of September 30, 2013: Results have been confirmed for those examined up to August 23)

   (2) The secondary examination
    Fukushima Medical University has been expanding the examination system, in an attempt to accelerate the implementation of the secondary examination. As a result, 73.6% of the 1,559 participants eligible for the secondary examination actually went through it, and 78.1% of them have completed it. ※5
    Also, in addition to Fukushima Medical University, two other medical facilities in Koriyama City and Iwaki City have been conducting the secondary examination since late July.
    Furthermore, out-of-prefecture facilities plan on conducting the secondary examination beginning in November 2013.

Progress status (as of September 30, 2013)

※5 Implementation status by municipalities is shown in Supplement 5.
● Priorities are given to those with urgent clinical needs.
● Regular follow-up examination, beginning April 2014, applies to those who were confirmed to be within the normal range (A1,A2) of the primary examination.
● Regular medical care applies to those who would need a close monitoring in about 6 months to 1 year (using national health insurance) and those who are confirmed to be beyond the normal range of A2.

3   Implementation of the full-scale examination
   The thyroid examination conducted from October 2011 through March 2014, considered the "preliminary examination," will continue as the "full-scale examination" beginning April 2014.
   Summary of the current "preliminary examination" and the improved features in the "full-scale examination" are described below.
   From now on, in order to engage in the maintenance and promotion of participants' health, implementation plans will be established to ensure the smooth and reliable examination with cooperation from the examination facilities inside and outside Fukushima Prefecture, the concerned academic societies and the related organizations.

(1) Summary of the thyroid examination

A. Summary of the preliminary examination

Targeted subjects

Fukushima Prefecture residents who were generally 18 or under at the time of the Great East Earthquake, specifically including those who were born between April 2, 1982 and April 1, 2011.

The primary examination

The examination to assess the current status of thyroid gland (mainly the presence or absence as well as the size of cysts and nodules) using the ultrasound diagnostic equipment.

Assessment results

Assessment A: (A1) No nodules or cysts.
                          (A2) Nodules 5.0 mm or smaller or cysts 20.0 mm or smaller. 
Assessment B: Nodules 5.1 mm or larger or cysts 20.1 mm or larger.
                            Moreover, A2 will be upgraded to Assessment B if the condition of thyroid gland warrants the secondary examination.
Assessment C: The thyroid gland condition warranting the immediate secondary examination.

The secondary examination

The examination conducted on those in need of more detailed tests as a result of the primary examination. It consists of ultrasound examination, blood and urine tests, and fine-needle aspiration biopsy when needed.

(For information)

The regular follow-up examination
Beginning April 2014, the regular follow-up examination (full-scale examination) will continue every 2 years up to age 20 and every 5 years after age 20.
Regular medical care
・A re-examination is conducted, as close monitoring, generally in 6 months to 1 year.
・Consists of examinations and/or medical procedures (such as surgery).

B. Improved features for the full-scale examination

(a) Targeted subjects
   In addition to the targets subjects in the preliminary examination, those born between April 2, 2011 and April 1, 2012 are to be included, giving rise to a total targeted subjects of approximately 385,000.
(b) The implementation period
   All targeted subjects are to be examined in two years from April 2014 to March 2016.
After that, the examination is to be conducted, on a long term, every 2 years up to age 20 and every 5 years after age 20.
(c) The implementation facilities
   The primary and secondary examinations are to be conducted by the examination facilities inside and outside Fukushima Prefecture as well as Fukushima Medical University.
(d) The primary examination implementation system
   Non-school age children, college students and adults will be examined mostly at the examination facilities within Fukushima Prefecture (examinations at public facilities to be concurrently carried out until the examination system is fully established), and elementary, junior high and high school students will be examined at the traveling examinations at schools. Non-Fukushima residents are to be examined at the out-of-prefecture examination facilities.
(e) The secondary examination implementation system
   In order to facilitate the secondary examination and improve the convenience for the participants, efforts will be made towards appropriate examinations at the examination facilities within and outside Fukushima Prefecture as well as Fukushima Medical University.

4.   Simplification of the information disclosure procedure for detailed information about the thyroid examination

   In regards to the self request for information disclosure relating to the thyroid examination, 
an easier process has been established. From now on, it will be conducted as below.

   (1) For the identity confirmation, submission of an extract of the family register is no longer required. As a rule, a copy of the examination notification sent tom Fukushima Medical University or the examination result notification is to be used for identity confirmation.

   (2) Multiple steps previously carried out by the person requesting information disclosure will be, as a rule, completed in one step.
   (3) No fee will be charged for the information disclosed.

Details are to be posted on the home page of Radiation Medical Science Center for the Fukushima Health Management Survey at Fukushima Medical University , http://fukushima-mimamori.jp/.

26 Thyroid Cancer Cases Confirmed in Fukushima Children: Preliminary Results of FY2011-2013 Thyroid Ultrasound Examination

Thirteenth Prefectural Oversight Committee convened on November 12, 2013, releasing the results of the latest thyroid examination as part of the prefectural health management survey.

Please refer to this post for complete translation of the full results.  

A summary of the results is provided below:

Total number of children examined as of September 30, 2013: 289,960

Total number of children whose initial examination results are confirmed: 225,537
(up to the August 23rd, 2013 examination)
     Assessment A1  121,525 (no nodules or cysts found)
     Assessment A2  102,453 (nodules 5.0 mm or smaller or cysts 20.0 mm or smaller)
     Assessment B     1,558 (nodules 5.1 mm or larger or cysts 20.1 mm or larger)
     Assessment C         1 (requiring immediate secondary examination)

Secondary examination includes more detailed thyroid ultrasound, blood and urine tests, and fine-needle aspiration biopsy if warranted.
      1,559 are eligible for secondary examination
      1,148 have actually undergone secondary examination
        897 finished the secondary examination

In summary, as of September 30, 2013, 26 thyroid cancer cases are confirmed and 32 have suspicious biopsy results. (As of July 31, 2013, there were 18 confirmed and 25 suspected cases).

During the committee meeting, Shinichi Suzuki, the head of the thyroid examination, mentioned that one of the 26 confirmed cancer cases was not papillary thyroid cancer: This case is undergoing cytological reevaluation to determine the subtype of thyroid cancer.

During the press conference following the committee meeting, no information was given, as to the details of individual cancer cases, such as the presence of lymph node metastasis or the type of surgery done.

Shinichi Suzuki maintains that this thyroid examination was originally initiated to assess the baseline thyroid condition of Fukushima children, as there is no such epidemiological data available in Japan, with an understanding that it was not possible to obtain pre-exposure data. It is being conducted on an assumption that the effect of radiation exposure would not be obvious for at least four years after exposure, as was seen after the Chernobyl accident.

If these cancer cases were indeed screening effects, similar malignancy would have to be expected in other parts of Japan. As for the thyroid survey conducted by the Ministry of Environment in Aomori, Yamanashi and Nagasaki Prefectures, widely recognized as a comparison study, no cancer data is available from the cases of thyroid ultrasound abnormalities detected. Also it is not age- and gender-matched, and there is a question about the possibly uneven quality of ultrasound examination itself between the two studies. The MOE spokesperson indicated that abnormal cases are undergoing further examination, and more data might become available for comparison.

Fukushima Parks: One-hour Time Limit for Playing

These photos were taken by Akemi, a single mother who had voluntarily evacuated from Fukushima City to Kyoto, over 500 km away, when she visited her parents' home in Fukushima City in March 2013.

What the sign says:

For those using the park:
Due to the effect of environmental radioactivity, please be careful of the following points in using the park.

  • Please limit the use of the park to 1 hour per day.
  • Please wash your hands and face and gargle after using the park.
  • Please be careful not to put soil and sand in your mouth.
For inquiry, contact Fukushima City Parks and Greenery Division Phone 525-3765

This is the park where the sign is posted. Akemi says identical signs were posted at three parks near her parents’ house. The sand pit is covered with blue tarp and weighted down. Akemi says this park used to be a green park. Akemi had sent her son to Kyoto by himself first, but while she was visiting him in Kyoto for a week in August 2012, the green park was turned into a regular playground. Was it part of the decontamination effort? Akemi says there is a child who walks through this park every day on the way to school.

This photo, taken from a slightly different angle, reveals a part of the body of a green and white heavy-duty excavating equipment visible in the upper left.

From yet another angle, the photo reveals what appears to be a construction site above the park. In fact, there is a house being built there.

Akemi got closer to the construction site to shoot this photo. The Radex radiation detector shows, "0.52 μSv/h."

Any park will have official air dose rates displayed after decontamination. The sign at this park states the measurement was taken on March 11, 2013, and the air dose rate is 0.186 μSv/h. However, Akemi's Radex registers 0.49 μSv/h, nearly 2.5 times as high as the official air dose rate.

Incidentally, Fukushima television stations show "Fukushima environmental radiation levels" as in this photo, accompanied by light and easy music, as if it were weather forecast.


By the way, these signs have been posted at various locations in Fukushima City since April 25, 2011.

This is a translation of a Kyodo article dated April 25, 2011.

Signs posted at Fukushima City parks caution radiation levels exceeding the regulatory limit

Fukushima City installed sign posts at two of its parks on April 25th, where the atmospheric radiation level exceeding the national regulatory limits (3.8 μSv/hr) was detected, warning park visitors, "Please limit the use to about one hour daily," and the sandpit was covered with blue tarps.

Despite the distance of over 60 km from Fukushima Daiichi nuclear power plant, "Shinobuyama Children's Forest Park" had an atmospheric radiation level detected at the same level as the national regulatory limit. Usually there are many children's voices echoing at the park where many visitors flock to admire cherry blossoms, but there was hardly anybody there.

A worker at the Fukushima City Parks and Greenery Division said, "We have been trying to make it a good park." And a neighbor woman (age 78) said with tears in her eyes, "It is lonesome not to be able to hear children's voices. We never had such a quiet spring. This nuclear accident is just so disappointing."

A similar sign post was installed at the Shinhama Park in the central part of the city where the radiation level was 0.1 above the regulatory limit (of 3.8 μSv/hr).

Rules imposed for the neighborhood park limits children’s playtime to one hour.

The radioactive fallout due to the accident is called "environmental radiation" as if it were part of nature.

Discrepancies exist between the official air dose rate after decontamination and the level detected by a personal radiation detector.

A house is being newly built right near a park with a daily one-hour time limit. (Incidentally, the real estate market is apparently "hot" in Fukushima City, as those who evacuated from Hama Dori, or eastern part of Fukushima Prefecture, look to settle there).

Certainly, there are individual stories and circumstances about their reasons to remain where children can barely be outside. However, seeing these photos makes you wonder about the consequences.

Note: A photo of a sign from Sakabuta Park in Koriyama City, Fukushima, mentioned to be from April 2013, was deleted as of November 16, 2013 due to the following reasons.

  • Current air dose levels are not consistent with what is on the sign.
  • The photo was obtained from a tweet, and its original source is uncertain.
This oversight is deeply regretted.

Fukushima Doctors Planned to Distribute Stable Iodine to Every Fukushima Resident in Vain

Note: The original title, "Fukushima Doctors' Plan to Distribute Stable Iodine to Every Fukushima Resident Thwarted by NIRS and Yamashita" was changed to "Fukushima Doctors Planned to Distribute Stable Iodine to Every Fukushima Resident in Vain" on November 9, 2013, according to the further development of the story in "Prometheus Trap" series.

Asahi Shimbun's revealing "Prometheus Trap" series has been featuring previously unpublicized stories surrounding the Fukushima nuclear accident and its aftermath. Its latest series, called "Doctors Advance on Frontline," describes what was going on at Fukushima Medical University shortly after the Fukushima nuclear accident began to unfold.

Excerpted and translated from "Prometheus Trap: Doctors Advance on Frontline #18, #19 and #20," published on November 5, 6, and 7, 2013, respectively.


Fukushima Medical University is located in Fukushima City, 60 km west of Fukushima Daiichi nuclear power plant. Fukushima Medical University Hospital staff was not uninformed and inexperienced about the care of radiation-exposed patients despite its designation as a radiation exposure medical care facility. The hastily set up decontamination station was ill-equipped and poorly-staffed. In fact, physicians on staff at Fukushima Medical University Hospital felt betrayed and overwhelmed that, instead of the "super team" of radiation specialists promised to come to take care of the radiation exposed individuals, the burden was heavily and mercilessly placed upon their inexperienced shoulders. Anxiety and fear mounted amongst the staff, with some, especially women, wanting to leave the hospital and evacuate with their children. 

Meanwhile, Fukushima Medical University’s own disaster response headquarters, located in the hospital president's office, began to consider the distribution of stable iodine to residents after the radiation levels at the entrance to Fukushima Daiichi nuclear power plant increased on March 12, 2011. Stable iodine saturates the thyroid gland with nonradioactive iodine to prevent the radioactive iodine uptake by thyroid gland, thus preventing radiation-induced thryoid cancer. Thyroid cancer incidence skyrocketed, especially in young children who rarely develop thyroid cancer, after the Chernobyl accident in 1986. Vice president of the hospital and pediatrician, Mitsuaki Hosoya, thought residents must be really anxious about the situation, considering that hospital staff evidenced fear of radiation. He thought they needed to establish a system for immediate administration of stable iodine to residents in case the need arose. They decided to have neighborhood pharmacies administer stable iodine, which would allow every Fukushima resident to take it.

On March 13, 2013, the head of the hospital pharmacy contacted the president of Fukushima Pharmacist Association, who immediately agreed to cooperate and quickly faxed an instruction on how to make iodine syrup for babies and infants to 850 pharmacies in Fukushima Prefecture. The hospital pharmacist learned from Fukushima Prefecture that there were 240,000 stable iodine tables and 6 kg of stable iodine powder, and additional 500,000 were being ordered. The pediatrics department at the hospital already knew how many children had evacuated from areas near the Fukushima Dai-ichi nuclear power plant: these children would be needing the stable iodine the most. They had decided to tell the residents on television to go to the nearest pharmacy for the stable iodine distribution and administration.

On March 14, in the midst of the preparation for the stable iodine distribution, National Institute of Radiation Sciences (NIRS) published a statement, forbidding the consumption of gargling medicine containing iodine as well as telling the public the stable iodine can only be taken at specified locations only if ordered. 

However, Hosoya was prepared to ignore this statement, thinking the danger of thyroid cancer weighed more than the potential side effects, if the need ever arose.

Also in the morning of March 14, 2011, Fukushima Medical University administrators began to look for someone who could explain the danger of radiation to the staff to calm their fear of radiation. Shinichi Suzuki, an endocrine surgeon, said Shunichi Yamashita, an endocrinologist at Nagasaki University, who conducted thyroid research in Belarus after the Chernobyl accident, was "the only person who could explain about radiation in an easy-to-understand yet scientific manner." An official arrangement between Nagasaki University and Fukushima Prefecture was made for Yamashita to come to Fukushima Medical University, upon an official request by Fukushima Governor,  to present accurate scientific knowledge of radiation.

Meanwhile, Fukushima Medical University was distributing stable iodine to the staff members in order to calm the fear, anxiety and confusion amongst them, especially in young women and those with children. Top priority was given to medical staff under age 40 who would be engaged in medical care of the radiation-exposed and personnel who were taking radiation measurements in the hospital. Next in line was staff in outpatient clinics under age 40, followed by female staff under age 40. The top priority group was given stable iodine beginning on March 12, out of 1,000 tablets in stock. By noon on March 15, 4,507 tablets were distributed as more stable iodine tablets came in from the pharmaceutical wholesaler. 4,000 tablets were received from Fukushima Prefecture on March 15, 2,000 more from the wholesaler on March 16, allowing distribution to Fukushima Medical University teaching faculty and office personnel. The timing of administration was left up to each work site, but many apparently took it as soon as it was distributed.

After a Hiroshima University professor from the acute radiation exposure medicine management headquarter set up by the Ministry of Education, Culture, Sports, Science and Technology told them there was a potential danger of Unit 4 exploding in the evening of March 15, a decision was made to distribute the stable iodine to children of the staff. Children were to be administered the stable iodine either "at the time of explosion" or "when the air dose rate is 100 μSv/h." 

Everyone at Fukushima Medical University was to keep secret the fact the stable iodine was distributed.

Although the hospital staff appeared to calm down after the distribution of stable iodine,  Fukushima Prefecture was not giving them permission for administration of stable iodine to residents as planned by the vice president of the hospital, Hosoya. He had to leave the decision to Shunichi Yamashita, who was to come to Fukushima Prefecture on March 18.

At 6 pm on March 18, Shunichi Yamashita did a presentation, along with two colleagues, Naoki Matsuda and Noboru Takamura, to about 300 staff members of Fukushima Medical University in a large conference room. Yamashita focused on the presumed necessity of stable iodine, insisting that it was not necessary to administer stable iodine: 

1) Prevention of thyroid cancer by stable iodine is a misunderstanding and nothing more than "Iodine belief." Japanese people's thyroid glands would only absorb 15 to 25 % of radioactive iodine, whereas Belarusians would absorb 40 to 50 % of radioactive iodine.
2) Exposure dose to radioactive iodine in the 20 km zone and west of the 30 km zone would most likely be below 1 mSv. As this is significantly less than Chernobyl, the Japanese government would not order stable iodine administration.
3) The stable iodine administration manual  should not be used as it contains many errors.

At the end of his presentation, Yamashita told the staff, "Please don't run away. Radiation exposure from this accident is a fate of Japan which promoted nuclear power plants despite being earthquake-prone.

Although Yamashita appeared confident, not all staff members were convinced: some physicians were obviously angry that the hospital administration arranged the presentation specifically for the purpose of calming down and soothing the hospital staff.

Significance of this story is multi-layered.

Why Fukushima Medical University Hospital was singled out as the facility to decontaminate and care for the radiation-exposed and injured individuals is a mystery. The hospital staff was overwhelmed due to inexperience and wondered why more experienced NIRS didn't handle the matter. Apparently, patients often were transported to NIRS after decontamination and stabilization anyway, leaving the mess of radiation contamination to be dealt with by Fukushima Medical University.

The fact that stable iodine was distributed to the Fukushima Medical University Hospital staff might be reasonable, considering they were expected to fulfill their duty on site, no matter how badly the patients might be contaminated. It could be considered not so much the privilege of being at the medical institution as the necessity for integrity of medical care structure and maintenance of moral needed to face difficult tasks. However, the fact the staff was sworn to secrecy could appear to make it all about privilege. If it is any consolation, at least the hospital staff was seriously considering taking care of the community, ascertaining easy access for every Fukushima resident to stable iodine. It is extremely unfortunate their effort could not be carried out due to an "order" by NIRS, the institution with the knowledge and expertise in handling radiation exposure. NIRS, incidentally, was the institution that funneled the data to UNSCEAR, the United Nations Science Committee on Effects of Atomic Radiation, on behalf of the Japanese government. Just what data NIRS gave to UNSCEAR is unknown as the full version of the UNSCEAR 2013 Fukushima report is not to be published until January 2014. Curiously, the chairman of the board at NIRS, Yoshiharu Yonekura, is not only the representative of the Japanese delegation to UNSCEAR but also the UNSCEAR rapporteur for the next two years, which seems odd considering Japan is the country that is the subject of UNSCEAR's report.

The fact that the hospital staff was not allowed to execute their plan to distribute stable iodine to every Fukushima resident has potentially significant implications for children.

As of July 31, 2013, there are 18 Fukushima children confirmed with thyroid cancer and 26 more were awaiting excisional biopsy (meaning surgery to remove thyroid tissue) to confirm the equivocal result of fine-needle aspiration biopsy (meaning thyroid cells aspirated suggested they could be cancer cells). The majority of over 360,000 Fukushima children were never given stable iodine. It is anybody's guess if these thyroid cancer cases would have arisen if the children would have been given stable iodine prophylaxis. For the time being, the Fukushima pediatric thyroid cancer cases are officially considered to reflect "the screening effect" due to mass screening of asymptomatic children with the use of highly sophisticated ultrasound equipments. In addition, it is "officially too soon" for radiation-induced thyroid cancer to be detected, as the Chernobyl cases had latency of 4 to 5 years.

Curiously, Fukushima Medical University is reluctant to release any extra information about these cancer cases such as estimated exposure dose for each case, citing patient confidentiality. Shinichi Suzuki has repeatedly stated that these cancer cases are the result of screening effect and thus unlikely to be associated with radiation exposure. The Japanese government also insists that Fukushima's thyroid abnormalities are from the screening effect, considering similar percentages of thyroid ultrasound abnormalities discovered in the Ministry of the Environment (MOE) survey of three other prefectures, Aomori, Yamanashi and Nagasaki. For clarification, the MOE survey was not exactly age- and gender-matched to the Fukushima cohort, and there is some doubt about the standardization of the ultrasound procedure itself. (Parents have noted the Fukushima Medical University examination is very short, possibly not finding every abnormality that might be detected in a more thorough examination. In other words, the amount of time spent conducting the ultrasound examination might not be consistent between the Fukushima and the MOE cohorts). In addition, it should be the rate of thyroid cancer being compared between the two cohorts, not so much so-called B assessment indicating nodules equal to and larger than 5.1 mm or cysts equal to or larger than 20.1 mm, as some of these findings can turn out to be benign conditions.

Is it medically acceptable to be drawing such conclusions when the first round of thyroid examination has not even concluded? Or, is it merely their wishful thinking for it to be a screening effect?

The truth is, we may not be able to draw any definite conclusion until the first round of thyroid examinations in all Fukushima children is complete at the end of this fiscal year. The overall findings might well establish a new baseline for the actual prevalence of thyroid cancer for future comparison, if the current finding did indeed represent a screening effect. However, medically speaking, we should reserve any hasty judgement  and simply observe and record what we find, yet provide appropriate and compassionate medical care including any necessary tests to assess general health conditions of those exposed, not just limited to thyroid examination.

Needless to say, Yamashita's statement, "Please don't run away. Radiation exposure from this accident is a fate of Japan which promoted and built nuclear power plants despite being an earthquake-prone country." is not only inappropriate as a physician but deeply disturbing as a human being. It could very well have been the beginning of many other "statements" he would be making from this day on.

For now, we await the upcoming announcement of the latest results of the ongoing thyroid examination on November 12, 2013.
