Abstract: After the Chernobyl nuclear power plant accident, relatively high radioactive cesium levels were detected in various mushrooms produced in many countries. Mushrooms have a high transfer factor, showing a relatively high uptake of cesium from wood and soil in which they grow. In the present investigation, we analyzed radioactive cesium concentrations contained in the dried Lentinula edodes (Shiitake) produced in various prefectures all over Japan, and examined the effectiveness of this mushroom as an indicator of radioactive contamination of environment due to nuclear explosion tests and Chernobyl power plant accident.
