Beta nuclide in Osaka tap water spiked after typhoon

Typhoon17 (Jelawat) passed Japan on 9/30/2012.

On 10/1/2012, Osaka city measured the highest amount of beta nuclide in tap water, which was 0.45 Bq/L. This is the highest amount since 311. It is not announced what nuclides are specifically detected in this measurement.

(MHLW’s safety limit of Strontium 90 is 10 Bq/L. )

The chart below shows the historical amounts of beta nuclide in tap water. 0.45 Bq/L is the largest amount.


翌日の2012年10月1日、大阪市が計測した水道水のβ線量は0.45 Bq/Lとなり、最も高い値を記録しました。
(厚生労働省によるストロンチウム90の規制値は10 Bq/Lです。)
0.45 Bq/Lは最高値である事が見て取れます。

Le cyclone 17 (Jelawat) est passé sur le Japon le 30 septembre 2012.

Le 1er octobre 2012, la ville d’Osaka relève le plus haut niveau en bêta-nucléides dans l’eau du robinet, soit 0.45 Bq/L. C’est un record depuis le 11 mars 2011. Les nucléides spécifiquement détectés par cette mesure ne sont pas précisés.

(La limite de sécurité du MHLW pour le strontium 90 est de 10 Bq/L. )

Le graphique ci-dessous montre l’historique des niveaux de bêta-nucléides dans l’eau du robinet, 0,45 Bq/L est le plus haut.

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.
