Effects of species and geo-information on the ¹³⁷Cs concentrations in edible wild mushrooms and plants collected by residents after the Fukushima nuclear accident.

ABSTRACT: After the accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP), much of the wild and edible mushrooms and plants in the surrounding areas were contaminated with radiocesium (¹³⁷Cs). To elucidate their concentration characteristics, we analyzed ¹³⁷Cs radioactivity data in edible forest products brought in for food inspection by the residents of Kawauchi Village, 12-30 km away from the FDNPP, from 2012 to 2019. A Bayesian model to estimate ¹³⁷Cs concentration was constructed. Parameters of the normalized concentration of species (NC_sp) for mushrooms were similar to those of the same species obtained in a previous study. Although NC_sp values were highly varied among species, mycorrhizal mushrooms tended to have high NC_sp
