摘要： The dried sclerotium of the fungus Wolfiporia cocos is edible and has medicinal value. This study aimed to understand the accumulation of radioactivity arising from the alpha Po-210, and beta-emitting Pb-210, in the sclerotium's shell and core and assess a potential effective dose for consumers. Sclerotia were collected in the wild and from cultivars in China's Anhui and Yunnan provinces. The mean values of Po-210 activity concentration levels were 0.36 Bq kg(-1) dry weight in the core and 12.0 Bq kg(-1) dw in the shell; Pb-210 activities were 0.43 and 9.84 Bq kg(-1) dw, respectively. The potential effective radiation doses from core layers (as a major raw material of the sclerotium) ranged from 0.13 to 3.43 mu Sv kg(-1) dw from Po-210 decay and from 0.11 to 1.52 mu Sv kg(-1) dw from Pb-210 decay. Corresponding values for shell ranged from 0.80 to 42.4 for Po-210 and from 0.53 to 13.6 mu Sv kg(-1) dw for Pb-210. In general, the intake of W. cocos sclerotia varies between consumers, but this would not significantly change the effective radiation doses from Po-210 and Pb-210 isotopes. The consumption thus appears to be safe from a radiological protection point of view.
