Fukushima Prefecture and Fukushima Medical University Fail to Report a Thyroid Cancer Case

On March 30, 2017,  it was broadcast on both Fukushima and nationwide NHK channels that Fukushima Prefecture has not reported thyroid cancer diagnosed in a boy who was age 4 at the time of the 2011 Fukushima Daiichi nuclear power plant accident. The case came to light when the 311 Fund for Children with Thyroid Cancerrevealed he was one of six applicants that received aid in February 2017. (Video of the statement in Japanese on this website. See the section "Thyroid cancer cases outside Fukushima Prefecture" on this post for more information on the 311 Fund for Children with Thyroid Cancer).

The TUE, commissioned by Fukushima Prefecture to Fukushima Medical University, is conducted through the fund provided by the central government. The primary examination is screening by ultrasound. Those meeting certain criteria go on to the confirmatory examination where the majority end up being placed back on the regular screening schedule every 2-5 years. However, some are shifted to r…

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…
