Over 80 Bq/Kg of Cesium-137 detected from vacuum cleaner dust used since this Spring in Tokyo

On 8/18/2015, a citizen’s radiation measurement station reported that 81.4 Bq/Kg of Cs-137 was detected from vacuum cleaner dust in Tokyo.

The measurement station is called “Fujimiiru” located in Okayama prefecture.

The vacuum cleaner has been used since this May (3 months) in Itabashi ward of Tokyo.

Cs-137 density was 81.4 Bq/Kg. Absolute error was ± 18.7 Bq/Kg. Cs-134 density was lower than the detectable level (< 11.9 Bq/Kg).

Plus de 80 Bq/kg de césium 137 dans les poussières d’un aspirateur utilisé à Tokyo ce printemps dernier

 

Le 18 août 2015, une station privée de surveillance de la radioactivité rapporte avoir relevé 81,4 Bq/kg de Cs 137 dans les poussières d’un aspirateur de Tokyo.

La station privée se nomme “Fujimiiru” et se situe dans la préfecture d’Okayama.
L’aspirateur a été utilisé depuis mai dernier (3 mois) dans le quartier d’Itabashi de Tokyo.
La radioactivité en Cs 137 est de 81,4 Bq/kg. L’erreur absolue est de ± 18,7 Bq/kg. La radioactivité du Cs 134 est en-dessous du seuil détectable (< 11,9 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.
