171 Bq/Kg from a school playground sand in Kamakura city / Jumped up over 6 times as last year

On 10/20/2015, Kamakura city government announced they measured 171 Bq/Kg from the earth of a playground at an elementary school. The school name is Yamasaki Elementary School.

Cs-134 density was 31 Bq/Kg to prove this is from Fukushima accident. The sampling date was this August.

They collected the samples at 25 elementary schools and junior high schools. Cs-134/137 was detected at 22 of 25 schools.

The city government concluded in the report that the converted atmospheric dose is lower than the safety limit. However, the Cs-134/137 density was 26 Bq/Kg in 2014. It jumped up 6.6 times since last year. The possible reason is not mentioned in their report.

171 Bq/kg dans une cour d’école de Kamakura : 6 fois plus que l’an dernier


Le 20 octobre 2015, la municipalité de Kamakura a déclaré avoir relevé 171 Bq/kg dans le sol de la cour de récréation d’une école élémentaire. Cette école se nomme Yamasaki Elementary School.

La radioactivité en césium 134 était de 31 Bq/kg ce qui prouve que ça provient de la catastrophe de Fukushima. L’échantillon date d’août dernier.
Ils avaient pris des échantillons dans 25 écoles élémentaires et lycées. Une radioactivité au Cs-134/137 a été relevée dans 22 de ces 25 écoles.
Dans son compte-rendu, la municipalité conclus que la dose ambiante convertie est inférieure à la limite de sécurité. Néanmoins, la radioactivité au césium 134/137 était de 26 Bq/kg en 2014. Elle s’est multipliée par 6,6 depuis l’an dernier. Les causes possibles de cette augmentation ne sont pas mentionnées dans leur rapport.


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.
