Introduction: The risk of radioactivity addresses human life directly. The natural rock radioactivity is mainly due to 232Th, 238U), and 40K series. Activities involving blasting, crushing, and processing of rocks into numerous pieces lead to release of radionuclides into the atmosphere in the form of dust particles. M...

Introduction: Considering the risk of radiation, the measurement of the natural radiation sources seems to be necessary. In this study, the concentrations of the natural radionuclides, namely 226Ra, 232Th, and 40K, were measured in the soil samples taken from different locations of Golestan, Iran. The measurement results can also be used as a baseline to evaluate the impact of non-nuclear activ...
