内容記述 | Ingestion of edible wild mushrooms collected in areas contaminated with radiocaesium released from the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident may pose a risk of internal dose of the consumers. Species specific aggregated transfer factor (Tag), which is calculated using radiocaesium concentration in a wild mushroom species (Bq kg-1 wet mass [WM]) divided by the total concentration in the soil surface area (Bq m-2), would be a useful tool to estimate the dose from wild mushrooms by ingestion. In this study, we especially focused on the Tag data collected after 2016 to use these values for a long-term dose assessment. It was implied that concentrations of 137Cs after that year were almost the same, thus soil-mushroom system would be in apparent steady-state condition. Finally, we could obtain Tag values of 137Cs in 44 edible wild mushroom species native to Japan. The geometric mean (GM) values were 1.7×10-3 m2 kg-1 WM for saprobic type species (460 Tag data) and 6.2×10-3 m2 kg-1 WM for mycorrhizal type species (447 Tag data). On average, GM of species specific Tag values were 1.9±0.9 times higher to those reported in a previous study of wild mushrooms observed after the FDNPP, probably due to the different approaches for Tag calculation. | |||||
