NRA’s data shows contamination level in Tokyo tap water higher than Fukushima by 24 percent

According to NRA (Nuclear Regulation Authority), Cs-134/137 density in Tokyo tap water is 24% higher than Fukushima.

The report was released on 10/30/2015, titled as “Readings of radioactivity level in drinking water by prefecture” to cover from July to September in 2015.

From this report, only 0.0015 Bq/Kg of Cs-137  was detected in Fukushima drinking water. Cs-134 was not supposed to be detected. On the other hand, 0.00036 Bq/Kg of Cs-134 and 0.0015 of Bq/Kg were detected from Tokyo drinking water.

The measurement of Cs-134 is due to Fukushima accident.

NRA comments each data is based on the reports from prefectures.

It is not mentioned by Fukushima prefectural government why Cs-134 was not detected in their drinking water.

Les données de la NRA révèlent que la contamination de l’eau du robinet de Tokyo dépasse de 24 % celle de Fukushima


Selon la NRA (Nuclear Regulation Authority), la radioactivité en Cs 134/137 de l’eau du robinet de Tokyo dépasse de 24% celle de Fukushima.

Le rapport a été publié le 30 octobre 2015 sous le titre “Readings of radioactivity level in drinking water by prefecture” (= Relevés de radioactivité des eaux du robinet par préfecture) sur une période s’étendant de juillet à septembre 2015.
Selon ce rapport, les eaux potables de Fukushima n’auraient présenté que 0,0015 Bq/L de Cs 137. Le Cs 134 n’aurait soi-disant pas été détecté. De l’autre côté, ils auraient relevé 0,00036 Bq/L de Cs-134 et 0,0015 of Bq/L dans les eaux potables de Tokyo.
Le Cs-134 provient de la catastrophe de Fukushima.
La NRA déclare que chaque résultat est basé sur les rapports des préfectures.
La préfecture de Fukushima ne précise pas pourquoi il n’ont pas relevé de Cs-134 dans leurs eaux potables.

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.
