Mako Oshidori in Düsseldorf "The Hidden Truth about Fukushima"

On March 8th, 2014, comedienne/journalist Mako Oshidori gave a lecture, "The Hidden Truth About Fukushima" in Düsseldorf, Germany, organized by a citizen's group, SAYONARA Genpatsu Düsseldorf. Translation of Mako Oshidori's March 6th, 2014 press conference at the German IPPNW (International Physicians for the Prevention of Nuclear War) Symposium in Frankfurt can be found here.
The lecture, given in Japanese with German interpretation, was transcribed and translated into English.




Moderator: Good evening everyone. My name is Mariko. Welcome to a lecture by Mako Oshidori.

A huge earthquake, followed by tsunami and the nuclear accident, has become an unprecedented disaster for the Japanese as well as the rest of the world. Moreover, this accident is not only out of control but continues to be in critical state.
As you may be aware, the issue of anti-nuclear power p…

Radiation Testing of Canned Salmon Caught in the North Pacific Ocean Before and After the 2011 Fukushima Nuclear Accident

Below are the results of radiation testing on canned salmon produced by an American seafood company, Vital Choice Wild Seafood and Organics. (Here is the Japanese article).

Note
Becquerel (Bq) is a unit of radioactivity: 1 Bq means "one disintegration event per second."
Picocurie (pCi) is a unit of radioactivity: 1 pCi = 0.037 Bq

Highlights
In this citizen-driven project, Pacific salmon cans from a U.S. seafood company, Vital Choice Wild Seafood and Organics, underwent radiation testing by citizen labs in Japan. Salmon cans before and after the 2011 Fukushima nuclear accident (2009, 2011, 2012, 2014) were analyzed for 4 radionuclides: Cesium-134, Cesium-137, Strontium-90 and Tritium.A very small amount of Cesium-137 was detected in all 4 samples, mostly due to background Cesium-137 ("legacy Cesium-137) from nuclear weapons testing.The 2011 sample canned in August 2011 had a slightly higher level of Cesium-137 than the other 3 samples, and the difference of about 0.02 Bq/kg m…
