为了估算因食用蘑菇而摄入的放射性铯，对属于 11 个物种的约 100 个样品进行了分析，以确定食品市场上常见食用蘑菇中 137C 和 40K 的代表性值。 137Cs 的浓度范围为 <0.047-39 Bq kg(-1)（湿重），40K 的浓度范围为 30-210 Bq kg(-1)（湿重）。 137Cs 的中位浓度为 1.3 Bq kg(-1)（湿重），40K 的中位浓度为 97 Bq kg(-1)（湿重）。栽培蘑菇中的 137Cs 浓度明显低于野生蘑菇。根据分析结果和日本食品消费数据计算，每人每年通过蘑菇摄入的 137Cs 为 6.0 Bq（137Cs），约占该核素膳食总摄入量的 32%。 137Cs穿过蘑菇的有效剂量当量估计为7.7 x 10(-8) Sv（根据标准偏差估计的范围：3.0 x 10(-8) - 2.0 x 10(-7)）。
To estimate radiocesium intake due to eating mushrooms, about 100 samples belonging to 11 species were analyzed to establish representative values for 137Cs and 40K in common edible mushrooms available in food markets. Concentration ranges were <0.047-39 Bq kg(-1) (wet wt) for 137Cs and 30-210 Bq kg(-1) (wet wt) for 40K. The median concentrations were 1.3 Bq kg(-1) (wet wt) for 137Cs and 97 Bq kg(-1) (wet wt) for 40K. The 137Cs concentrations in cultivated mushrooms were markedly lower than those in wild mushrooms. The annual intake of 137Cs per person through mushrooms was calculated (using analytical results and food consumption data in Japan) to be 6.0 Bq for 137Cs, which is about 32% of the total dietary intake of this nuclide. The effective dose equivalent of 137Cs through mushroom was estimated to be 7.7 x 10(-8) Sv (range estimated from the standard deviation: 3.0 x 10(-8) - 2.0 x 10(-7)).
