Am-241 and Pu-238/239/240 measured from offshore Fukushima, Miyagi, Ibaraki, MEXT “Within normal range”

According to MEXT (Ministry of Education, Culture, Sports, Science and Technology), 0.54 ~ 0.71 Bq/kg of Americium-241 and 0.011 ~ 0.021 Bq/Kg of Plutonium-238, 0.96 ~ 1.4 Bq/Kg of Plutonium-239/240 were measured from the dry soil of the sea ground offshore Miyagi, Fukushima and Ibaraki.

 

Like every time they measure Actinoid Series Element from the samples from sea, MEXT states it’s within the range of the past density measurements.

・The results of the environmental radioactivity measurement in the marine soil in the sea area of Nuclear Fuel Cycle Facility at offshore of Aomori and Iwate Prefecture shown in the report “Oceanic Environmental Radioactivity Synthesis Evaluation Business” FY 2008-2010 :
Pu-239+Pu-240:0.41~4.4Bq/kg・dry soil
・The results of the environmental radioactivity measurement in the marine soil in the sea area of Nuclear Power Plant shown in the report “Oceanic Environmental Radioactivity Synthesis Evaluation Business” FY 2010 :
Am-241:0.22~2.1Bq/kg・dry soil

 

However, the samples were taken in August 2012. There is no explanation why they took 7 months to release the data.

De l’Americium 241 et du Plutonium 238/239/240 relevés au large de Fukushima, Miyagi, Ibaraki. Le MEXT : “C’est dans la fourchette”

 

Selon le MEXT (Ministère de l’Éducation, de la Culture, des Sports, de la Science et des Technologies), de 0,54 à 0,71 Bq/kg d’américium 241, de 0,011 à 0,021 Bq/kg de plutonium 238, de 0,96 à 1,4 Bq/kg de plutonium 239/240 ont été relevés dans des extraits secs du fond marin du large des préfectures de Miyagi, Fukushima et Ibaraki.

Comme à chaque fois qu’il relèvent des éléments de la série des actinides dans des échantillons de fonds marins, le MEXT affirme que c’est dans la fourchette des relevés passés.

“Les résultats des mesures de la radioactivité dans l’environnement des fonds marins de la région de l’océan autour de la centrale à combustibles nucléaires au large des préfectures d’Aomori et d’Iwate ont montré, dans le rapport “Oceanic Environmental Radioactivity Synthesis Evaluation Business” FY 2008-2010 :
Pu 239+Pu 240 :de 0,41 à 4,4 Bq/kg・extrait sec
Les résultats des mesures de la radioactivité dans l’environnement des fonds marins de la région de l’océan autour de la centrale nucléaire ont montré, dans le rapport “Oceanic Environmental Radioactivity Synthesis Evaluation Business” FY 2010 :
Am 241 : de 0,22 à 2,1 Bq/kg extrait sec”

Toutefois, les échantillons datent d’août 2012. Il n’y a pas d’explication fournie au fait qu’il leur a fallu 7 mois pour publier ces données.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
