A big present from my home town Yokohama to the world.
This is the measurement result of Strontium 90.
Measurement 9/1/2011
Analysis 9/2/2011
Strontium 90 195 Bq/Kg<???ストロンチウム90
Sample 605 g
Dust on the roof of an apartment in Kouhokuku Yokohama
Below is the bonus.
Cesium-134 29,775 Bq/Kg
Cesium-137 33,659 Bq/Kg<???セシウム合計63,434 Bq/Kg
Measurement 8/10/2011
Analysis 8/11/2011
Having measured Strontium-90 from the soil of Yokohama, we suspect it may contain plutonium too.
We took 200g of the same sample and sent it to Dr C.Busby.
As a result, it was not positive for plutonium nor americium but surprisingly 8400 Bq/Kg of lead 210 (pb-210)was measured.
Honestly we are puzzled by the result and don’t know what the potential risk will be.

横浜の土壌から8,400 Bq/Kg の鉛210が検出された。Dr Chris Busby:20Bq/kg程度であるべきなのに。沸騰点の低い鉛210が、大量に福島原発から放出されたのでしょう。ウラニウム-238が崩壊してできたものです。
