Radioactive Japan: Chiba, Lake Teganuma: 12,200 Bq/Kg

12,200 Bq/Kg from Teganuma lake Chiba (Fukushima Diary, July 4, 2012):

Chiba prefecture measured radiation at 19 points of Teganuma lake (195km from Fukushima) including 2 rivers to flow into Teganuma lake. The rivers run through hotspots, and they measured over 10,000 Bq/Kg from the ground soil of the bottom of rivers, where the rivers flow into the lake. The highest reading was 12,200 Bq/Kg. The measurement was done from 5/24 to 6/6/2012.

Fishery was allowed in the lake until this Spring. Having announced the high level of contamination on 7/3/2012, Chiba prefecture stated it’s not harmful because the radiation is shielded by lake water, which they didn’t detect radiation from.
