Abstract :
Background: Natural and artificial radioactive materials are the most important sources of radiation for human existing in all over the world, thus investigating their
radioactivity is of great importance because of their ionizing properties and harmful
effects on human health. Therefore, this study was conducted to measure
radionuclides concentrations of 226Ra, 232Th, 40K and 137Cs in sediment samples
collected from various hot springs in Kerman province and also determining received
annual effective dose. Materials and Methods: Thirteen sediment samples were
collected from different hot springs and concentrations of radionuclides in sediment
samples were measured via spectrometry method and using HPGe detector. To
evaluate radiation hazards caused by these radionuclides, radium equivalent activity,
absorbed dose rate in air, and annual effective dose of samples were calculated.
Results: Concentrations of 226Ra, 232Th, 40K and 137Cs in sediment samples varied from
21.01±0.71 to 193.16±1.72, 16.84±1.21 to 245.92±2.69, 90.13±3.37 to 667.81±14.59
