  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 in 2012, 2013 and 2014. The concentration of radioactive cesium was measured by means of the hyperpure germanium semiconductor detector. The concentrations were ranged from 35 to 600,000 Bq/kg, and were different with points of sampling and kinds. The transfer coefficient of radioactive cesium to most wild mushrooms are lower than 0.5, although some mushroom species concentrate environmental radioactive cesium more than twice.
