Sample : Snow (Taken from the roof of a car)
Sampling date : January 2012
Cs-134 : 14.9 Bq/Kg
Cs-137 : 15.3 Bq/Kg
Iodine-131 : 20.0 Bq/Kg
[Note] Every time they detect cesium-134/137 and iodine-131 from snow/rain including this case, some people comment it’s just Pb-214 and Bi-214. More analysis is needed. (1/23/2013)
