Introduction Artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. As such, humans and environments are at constant exposure of these radiation types. In this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. Materials and Methods In this study, natural and artificial radioactivity concentrations were determined in Agaricus bispora (nourished mushrooms), Cantharellus cibarius, Coprinus micaceus (wild fungi species) and their composts through gamma-ray spectrometryusinga high-purity germanium (HPGe) detector with 30% relative efficiency. Results Radioactivity concentrations of 238U and 232Th in edible mushroom samples were lower than the minimum detectable activity (MDA). For 40K and 137Cs, these concentrations were within the ranges of 1895.24-1920.24and
