180 times much as radioactive cesium detected in fish from Fukushima nuclear plant port

On the 5th of June, 2023, Tepco announced they detected 18,000 Bq/Kg of radioactive cesium from Black rockfish collected in the port of the crippled nuclear plant of Fukushima. 

This is 180 times much as the current food safety standard (100 Bq/Kg). 

Moreover, the detected 18,000 Bq/Kg of radioactive cesium consists of Cs-134 and Cs-137.

The half-life of Cs-134 is up to 2 years, nevertheless this black rockfish contained 380 Bq/Kg of Cs-134. Tepco has not publicly made an announcement regarding the detection of Cs-134.

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.
