Only 4 smelt samples collected in Haruna lake, 340Bq/Kg measured but fishing restriction is lifted


In Haruna lake of Gunma, the fishery corporative tried to collect the samples of Japanese pond smelt to analyze the radiation level. The smelt fishing is their main industry, but it has been restricted due to the radioactive contamination.
They need 50~100 samples of the fish to analyze radiation level, but they only collected 1 sample last year so they could not lift the fishing restriction.

This year, they only fished 4 samples but they managed to analyze radioactive material. (cf, Only 2 Japanese pond smelt caught from 3 days test fishing in Haruna lake Gunma [URL])
As a result, they measured 340 Bq/Kg, which is over the safety limit of food.

However, Gunma prefectural government is going to lift the fishing restriction with self-control on shipping. The fished Japanese pond smelt would have to be returned.

Seulement 4 éperlans d’eau douce pris dans le lac Haruna, 340 Bq/kg mais l’interdiction de pêche est levée

Dans le lac d’Haruna de Gunma, la corporation des pêcheurs a essayé de récolter des échantillons d’éperlans d’eau douce japonais pour en mesurer la radioactivité. La pêche à l’éperlan est leur principale activité mais elle a été restreinte à cause de la contamination radioactive.
Ils ont besoin de 50 à 100 échantillons pour déterminer leur niveau radioactif mais ils n’en ont pris qu’un seul exemplaire l’an dernier et n’ont pu lever l’interdiction de pêche.

Cette année, ils ont seulement pris 4 échantillons dont ils ont quand même analysé les éléments radioactifs. (cf. Seulement 2 éperlans d’eau douce pris en 3 jours de pêches de test dans le lac Haruna de Gunma [Lien1])
Le résultat est qu’ils ont relevé 340 Bq/kg, ce qui dépasse la limite de sécurité des aliments.

Malgré ce, la préfecture de Gunma va lever l’interdiction de pêche avec autocontrôle des expéditions. Les éperlans d’eau douce japonais devront être remis à l’eau.

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.
