Highly exposed workers increased 10 times from January to March in Fukushima plant

The number of Fukushima workers who were exposed more than 5mSv increased to 10 times from this January to March.

This is from Tepco’s report on exposure dose of Fukushima workers, which was published on 4/30/2015.


From this report, the workers who were exposed 5 – 20 mSv in January was 57. It increased to 327 in February and it became 585 in March.

The ratio to the total workers increased from 0.51% to 4.94% as well (Graph attached below).

The reason is not announced but this trend suggests increasing number of workers are sent to highly contaminated areas of Fukushima plant.

Entre janvier et mars, le nombre de travailleurs de Fukushima fortement exposés multiplié par 10


Le nombre de travailleurs de Fukushima exposés à plus de 5 mSv a été multiplié par 10 entre janvier et mars derniers. C’est dit dans le rapport de Tepco sur les doses d’exposition des travailleurs, publié le 30 avril 2015.

Selon ce rapport, il y a eu 57 travailleurs exposés entre 5 et 20 mSv en janvier. Ce nombre est passé à 327 en février et a atteint 585 en mars.
La fréquence sur le nombre total augmente également, de 0,51 % à 4,94 % (graphique ci-dessous).
La raison n’en est pas donnée mais cette tendance laisse penser qu’un nombre croissant de travailleurs est envoyé dans les zones extrêmement radioactives de la centrale 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.
