High levels of radionuclide activity concentrations in the agricultural soil in southern Iraq have been
recorded in 2017. These high ratios prompted us to conduct this work to evaluate the activity concentrations of
some radionuclides (238U, 232Th, 137Cs and 40K), and radiation hazard indices in therapeutic Iraqi bentonite mud
sold in the markets. 1 kg stone bentonite samples from the main local distribution markets in Baghdad were
selected. Each selected sample was prepared for gamma spectroscopy using high-purity germanium HPGe
detector. The activity concentrations measured in bentonite mud for 212Pb, 208Tl, and 228Ac which belong to
232Th series, 214Pb, 214Pb, and 214Bi that belong to 238U series, and for 40K, 137Cs radionuclides were low. Also, the
skin equivalent dose (
