Radioactive Japan

#Radioactive Japan: Food Items Exceeding
New Safety Limit (100Bq/Kg)


#Radioactive Japan: Food Items Exceeding
New Safety Limit (100Bq/Kg)

Farmers in contaminated areas in Fukushima, Miyagi, Iwate,
Tochigi, Ibaraki, Gunma, and Chiba continue to farm, and the government
is busy setting up one PR campaign after another to appeal safety of
things produced in Japan. The media do report, but unless your
information comes from the net only, the news gets buried in the
cacophony of mind-numbing small news of no significance on TV and print

Here’s the list of food items that I found which exceeded the new safety
limit of 100 becquerels/kg of radioactive cesium:


Shiitake mushrooms: 350 becquerels/kg from Murata-cho, Miyagi Prefecture


Bamboo shoots: 120 becquerels/kg from Kisarazu City, Chiba Prefecture;
110 becquerels/kg from Ichihara City, Chiba Prefecture


Bamboo shoots: 130 becquerels/kg from Sakae-cho, Chiba Prefecture; 170
becquerels/kg from Abiko City, Chiba Prefecture


"Komon Kasube" (common skete): 640 becquerels/kg, test fishing off the
coast of Iwaki City, Fukushima


Beef: 106 becquerels/kg from Shibukawa City, Gunma Prefecture (the
cattle had to eat the feed (rye) with 772 becquerels/kg of cesium…)


"Suzuki" (sea bass): 104 becquerels/kg in Sendai Bay, Miyagi Prefecture


Shiitake mushrooms: 146 becquerels/kg from Shirosato-machi, Ibaraki
Prefecture; 131 becquerels/kg from Sakuragawa City, Ibaraki Prefecture


"Wakasagi" (pond smelt): 426 becquerels/kg from Akagi Onuma in Gunma

Prefecture press release (4/5/2012) for meat
, and for

6: Miyagi
Prefecture press release

Prefecture press release
8: Kyodo

All these food items (except for No. 4) would have been freely sold and
bought, as "safe", under the old, provisional safety limit that was in
effect up till April 1, 2012. Checking the prefectures’ press releases,
there are many other whose cesium levels are barely under 100 becquerels/kg.

In case of Gunma Prefecture, they use NaI scintillation survey meter
with detection limit of about 30 becquerels/kg. Only when the meat is
found with cesium exceeding the rather high detection limit, they use
their germanium semiconductor detector.

This happened last month in March, but a kindergarten in Okazaki City in
Aichi Prefecture (whose governor is pushing Toyota to become the final
disposal site for disaster debris ashes) served lunch to
kindergarteners using dried shiitake with 1,400 becquerels/kg of
radioactive cesium from Ibaraki Prefecture
. 30 kilograms of these
shiitake are either in the markets or have already been purchased by
customers in Okazaki City. (NHK
