197 Bq/Kg of Cs-134/137 measured from sandals left outside since 2011 in Tokyo

197 Bq/Kg of Cesium-134/137 was detected from the sandals in Tokyo, according to a citizen’s radiation measurement station in Saitama.

This is approx. as double as the safety limit of food though no one eats sandals.

The error range is ± 40.4 Bq/Kg.


These sandals have been left outside since July. 2011. Cesium-134 density was 28.8 Bq/Kg, Cesium-137 density was 168 Bq/Kg.

197 Bq/kg de césium 134/137 dans des sandales restées dehors depuis 2011 à Tokyo


Selon une station privée de mesure de la radioactivité de Saitama, 197 Bq/kg de césium 134/137 ont été relevés à Tokyo dans des sandales.

C’est à peu près le double de la limite de sécurité alimentaire même si personne ne mange souvent de sandales.
La marge d’erreur est de ± 40.4 Bq/kg.

Ces sandales sont restées dehors depuis juillet 2011. La radioactivité en césium 134 e, est de 28,8 Bq/kg, celle du césium 137 de 168 Bq/kg.

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.
