Abstract

Abstract: This study analyzed activity concentration and annual effective dose of radionuclides 40 K, 137 Cs, 226 Ra and 232 Th of 44 mushrooms collected from local markets in Taiwan. The 40 K activity concentrations were 1570 ± 150 Bq/kg-dw ( Agaricus bisporus) > 1084 ± 183 Bq/kg-dw ( Flammulina velutipe) > 736 ± 150 Bq/kg-dw (Lentinula edodes). The activity concentrations of 226 Ra were 5.04 ± 2.43, 4.00 ± 2.40 and 3.43 ± 2.69 Bq/kg-dw, and 232 Th were 3.96 ± 2.18, 3.86 ± 1.43 and 2.90 ± 1.99 Bq/kg-dw for F. velutipe, L. edodes and A. bisporus, respectively. In seven of the 44 samples, 137 Cs activity concentrations were detected, and the samples had an average of 1.55 ± 1.75 Bq/kg-dw. The total annual effective dose ranged from 0.90 to 3.50 μSv/y, with an average of 1.94 ± 0.62 μSv/y at an ingestion rate of 0.235 kg-dw/y.
