On the 1st of February, 2022, the Nuclear Regulation Authority of Japan published a report regarding the radioactivity concentration in seawater. The report is based on the press release of Tepco.

According to this report that reflects the latest oceanic situation after the Fukushima nuclear accident, gross beta nuclides have been detected every day at least since the 29th of December, 2021 except the 16th of January, 2022, when no samples were collected due to bad weather as Tepco stated. The concentration level of gross beta nuclides has consistently been above the safety limit in drinking-water defined by World Health Organization (WHO), which indicates 1Bq/L. The detected concentration level was eight to 14 times higher than the safety limit in every sample. The analysis was implemented in the evaporation drying method.
The sampling location was 1km south of Fukushima nuclear plant. The seawater samples were collected from merely the outer layer, and no data is released about the samples near the bottom of the sea, where it is assumed to highly concentrate the radioactive nuclides from the Fukushima plant.

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.
