12 Thyroid Cancer Cases Confirmed in Fukushima Children: Preliminary Results of FY2011/FY2012 Fukushima Thyroid Examination

The Eleventh Planning Committee of the Prefecture Health Management Survey met on June 5, 2013.  The preliminary data for the thyroid ultrasound examination was released to the press at the meeting.

Overall, a higher percentage of Fukushima children, tested in the Fiscal Year Heisei 24 (FY2012), are showing thyroid ultrasound abnormalities than the Fiscal Year Heisei 23 (FY2011) in all assessment categories.  In addition, the average diameter of the tumor increased.

Higher percentages of children have nodules larger than 5.1 mm or cysts larger than 20.1 mm, which put them in the assessment B category, qualifying for the secondary examination consisting of thyroid blood tests, a more detailed thyroid ultrasound examination, and a fine-needle aspiration biopsy if warranted.

The press is reporting that there are 28 cases suspected of thyroid cancer out of 174,000 children tested and that 12 of the 28 have been confirmed to have papillary thyroid cancer.  This is a bit misleading, as not all…

Radiological Analysis of Namie Street Dust

Jun Ohnishi from Ibaraki Prefecture sent a sample of highly radioactive street dust from Namie, Fukushima, to Marco Kaltofen for analysis.

From Jun Ohnishi:
The sample was collected at the coordinate 37.4752, 140.9461. The address is 102-1 Shimizu Onoda Namie-machi, Futaba-gun, Fukushima Prefecture.

Onoda district is designated as the "restricted zone," but anybody can enter without permission.  If you proceed westward about 50m past the collection point, you come to a barricade at the entrance to the "exclusion zone."
Here's the video showing the actual collection of the sample.  "2013.4.6 Namie street dust 86.09 μSv/h at 1 cm above ground"

A Letter to the Editor Regarding the Congenital Hypothyroidism Study by Mangano and Sherman

Alfred Körblein wrote this letter to the editor of OJPed in response to the study by Mangano and Sherman.  However, he was notified by the OJPed that the journal did not accept a letter to the editor.
The letter was also sent to both authors, Mangano and Sherman.  Mangano never replied, and Sherman only sent a cursory thank you, merely acknowledging the receipt of the e-mail. PDF 

Letter to the editor of OJPed in response to:
Joseph J. Mangano, Janette D. Sherman. Elevated airborne beta levels in Pacific/West Coast US States and trends in hypothyroidism among newborn after the Fukushima nuclear meltdown. Open Journal of Pediatrics, 2013, 3, 1-9.
Alfred Körblein,
Mangano and Sherman’s idea to study congenital hypothyroidism (CH) case numbers among newborn babies is new and seems to be promising. Their approach is reasonab…

A Rebuttal to the January 11, 2013 Article by James Conca, "Like We've Been Saying -- Radiation is Not A Big Deal," Posted on Forbes Website

(This article was originally posted on February 6, 2013 in the original FukushimaVoice site).                        Japanese version:

In the January 11th Forbes article titled “Like We’ve Been Saying--Radiation Is Not A Big Deal,” the author, James Conca, claims that “the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has finally admitted that we can’t use the LNT (linear no-threshold dose) hypothesis to predict cancer from low doses of radiation.”

He refers to the “UNSCEAR 2012” as the source of information.  His claim is that “radiation doses less tha…
