A surface soil sample was personally taken from the edge of the hard standing in the car park by a church in Aizu Wakazumi in July 2011. Aizu Wakazumi is approximately 100km west of the Fukushima Daiichi plant.

The Uranium-238 daughter Thorium-234 and Uranium-235 daughter, Thorium-231 were measured in this sample, which means Uranium-235 and -238 were here as well.

A sample will be sent for Mass spectrometry (ICPMS) to follow this up.

The total Uranium concentration is also quite high at 112 Bq/kg (expected is about 10 to 20 Bq/kg). The matter of the Uranium contamination requires more research.
