Highest level of cesium detected in wild mushroom
Tochigi Prefecture announced on August 6 that 31,000 Bq/kg of radioactive cesium was detected in wild “Lactarius volemus” (tawny milkcap mushroom) harvested in Nikko City, far exceeding the national safety standard (100 Bq/kg).
According to the Ministry of Health and Welfare, it is the highest level exceeding the amount detected in “Lactarius volemus” harvested in Tanakura-machi in Fukushima Prefecture in September last year, which measured 28,000 Bq/kg. The Tochigi prefectural government says, “We believe the cesium absorption was largely from the soil, but radioactive materials from the surrounding trees may also have affected it.”
