Abstract :In this study it was determined the specific activities of some important radionuclides such as thorium ( 232 Th), uranium ( 238 U), potassium ( 40 K) and cesium ( 137 Cs), accumulated in Agaricus bisporus and Pleurotus ostreatus commercial mushrooms and in their compost. Additionally, the annual effective dose received by individuals was calculated. 137 Cs activity was not detected. In both mushroom species obtained from different firms; the specific activity concentration of 232 Th, 238 U, 40 K ranged from 2.1 ± 0.2 to 9.2 ± 0.7, 14.6 ± 1.3 to 26.6 ± 1.8 and 330.4 ± 18.3 to 739.7 ± 25.2 Bq/kg, respectively and in their compost 11.0 ± 0.6 to 19.1 ± 0.9, 27.8 ± 1.2 to 45.1 ± 2.7, 126.7 ± 5.2 to 304.5 ± 12.7 Bq/kg, respectively. Among the Agaricus species, the highest 232 Th and 238 U activity concentration was seen in the mushroom obtained from D firm. The highest 40 K activity concentration was detected in the mushroom provided from A firm. The lowest 238 U and the the highest 232 Th concentrations were in Pleurotus ostreatus. In conclusion, all investigated parameters revealed that there was no any health risk in both mushroom species cultivated in different firms.Keywords : Radioactivity, effective dose, cultivated mushroom
