Radioactive silver and Sr-90 measured from marine products of Fukushima, silver higher than cesium in 62% of samples

On 11/30/2012, Tepco released the radioactive nuclide analysis of marine products.

From the report, Ag-110m (radioactive silver) and Sr-90 were measured from crabs, common skete, and barfin flounder.
Especially the half life of Ag-11om is only 250 days, but the reading was higher than Cs-134/137 from 13 of 21 samples. (62%)
Also, the “-” in the Sr-90 section means “Not tested”, which doesn’t mean “ZERO Bq/Kg”. There is no explanation why Tepco didn’t measure Sr-90 of those samples.

De l’argent et du Sr-90 radioactifs relevés dans des pêches de Fukushima, plus d’argent que de césium dans 62 % des échantillons

 

Le 30 novembre 2012, Tepco publie l’analyse des nucléides de produits marins.
Selon ce rapport, de l’Ag-110m (argent radioactif) et du Sr-90 ont été relevés dans des crabes, des raies communes et des soles.
En particulier, la période de l’Ag-11om n’est que de 250 jours mais le relevé était au-dessus du Cs-134/137 pour 13 des 21 échantillons. (62%)
De plus, le “-” dans  la colonne Sr-90 signifie “Non testé”, ce qui ne veut pas dire “ZERO Bq/kg”. Aucune explication n’est donnée sur la raison pour laquelle Tepco n’a pas recherché le Sr-90 dans ces échantillons.

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.
