0.92 microSv/h from St.Louis

They are concerned that plume flies from Japan to America.

Though it is not sure that it’s from Japan, they measured 3.7 times higher level of radiation from snow in St. Louis than usual on 2/13/2012.



The person who posted this video commented like this below..

Count returning between 74cpm and 110cpm.. normal levels are 20-30cpm (as indicated by past tests done at the same location).


(If the conversion is not correct, please leave me a comment)

74CPM = 0.62 microSv/h

110CPM = 0.92 microSv/h


It’s sure that they measured about 3.7 times higher level of radiation than usual.

It seems better not to let children play in the snow.

I expect someone to analyze the nuclide of this snow.
