On 23 June 2012, I measured radiation at a riverside of WATARASE river in Fukushima city of Fukushima prefecture, Japan.

The monitoring point is central area of Fukushima city, near the bridge of national road route 4 across the river, only 200m for Fukushima prefectural government office, and 55km from Fukushima Daiichi Nuclear power plant.

There are rain water drainage ditches into ABUKUMA river from “WATARI”, a housing area of Fukushima city.

I monitored 0.45 micro Sievert per hour in air at my breast height of the river water’s edge.

15.70 in air at 100cm high near mud of the drainage ditch, 85.03 micro Sievert per hour on the mud.
