Abstract
[Abstract] Large amount of radioactive cesium was emitted from the TEPCO Fukushima Dai-ichi nuclear power plant by the accident into atmospheric air, and a part of the radioactivity was brought to the ground by rain and snowfall. The Yamakiya district in Kawamata-machi, Fukushima is specified as the prepared evacuation zone. The authors collected wild mushrooms in this district as samples with gentle guide of local mushroom lovers in October, 2012. The kinds of mushroom were specified by the mushroom specialist. 16 kinds of mushrooms have been extracted. The extracted mushroom was brought back to the university. The concentration of radioactive cesium was measured by means of the hyperpure germanium semiconductor detector. The concentrations were ranged from 0.5 to 2600 Bq/g, and were different with points of sampling and kinds. The concentrations were compared with before washing and after washing by means of ultrasonic cleaning. The amount of radioactive cesium reduced to the range from 30% to 60% of the before washing.
