Plutonium-239/240 measured from offshore Fukushima, Tepco “It’s within historical range, not from Fukushima”

According to the radioactive material in seawater analysis report published by Tepco on 1/18/2013, plutonium-239/240 were measured from seawater samples offshore Fukushima.

3km offshore from Ukedogawa : (5.8+-1.8) ×10^-6 Bq/L
3km offshore from Fukushima Daini : (9.0+-2.3) ×10^-6 Bq/L

Tepco states they used to measure Pu-239/240 up to 1.3 ×10^-5 Bq/L from 2001 to 2008, this amount of Plutonium is within the historical range. It’s can’t be proven to be from Fukushima.

Du plutonium 239/240 au large de Fukushima, Tepco : “C’est dans les niveaux historiques, pas Fukushima”

Selon le rapport d’analyse des matières radioactives dans les eaux de mer publié par Tepco le 18 janvier 2013, du plutonium 239 et 240 a été relevé dans les échantillons pris au large de Fukushima.

3 km au large de Ukedogawa : (5,8+/-1,8) ×10^-6 Bq/L (0,0000058 Bq/l)
3 km au large de Fukushima Daini : (9,0+/-2,3) ×10^-6 Bq/L (0,000009 Bq/l)

Tepco affirme qu’ils relevaient habituellement du Pu 239/240 jusqu’à 1,3 ×10^-5 Bq/L (0,000013 Bq/l) entre 2001 et 2008, cette quantité de plutonium est dans les niveaux historiques. On ne peut prouver que ça vient de Fukushima.

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.
