“…In a study conducted by Jomehzadeh et al, on Amireh Keykhosravi, Chamanrang, Hormak, Jooshan, Khodadadi, Maskoun and Shirinak hot springs in Kerman province, in which RDS-110 survey meter device was used, values of annual effective dose in these hot springs were measured to be 1.16, 0.79, 0.97, 0.49, 0.88, 0.79 and 0.97 in mSvy -1 , respectively (3) , while in the present study, in which HPGe detector was used, annual effective dose in these hot springs were obtained to be 0.43, 0.53, 0.39, 0.17, 0.39, 0.39 and 0.37 in mSvy -1 , respectively, and also comparison of these results showed that in this study, annual effective dose of all hot springs has decreased.…”

“…Hence, investigation on presence of various contaminants including natural and artificial radioactive substances in the water is of particular importance (1,2) . Although, it is mostly believed that ionizing rays are received from irradiations of artificial and man-made sources, but in fact, most people in the community are exposed to these irradiations via natural radioactive sources in normal conditions (3,4) . Environmental natural radioactivity and its external radiation mainly depend on geographical and geological conditions of the site, which may vary in each region throughout the world (5) .…”

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 226 Ra, 232 Th, 40 K and 137 Cs 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 226 Ra, 232 Th, 40 K and 137 Cs 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 and

“…Kozłowska, et al, in a study conducted in Poland, reported that amounts of annual effective dose of absorbed were between 0.003 -1.1 in mSvy -1 for spring and well water (10) . Hot springs are natural features of Kerman province, and therapeutic properties of these hot springs encourage the officials of the province's tourism industry to identify and enhance tourism facilities for hot springs (11) . Therefore, this study was conducted to measure radon-222 concentration and to determine annual effective dose of inhalation in the vicinity of hot springs of Kerman province.…”

Background: Human exposure to Radon-222 gas is one of the most important natural radiation sources of radioactive gases, and inhalation of this gas and its decay products can cause lung cancer. Therefore, this study was conducted to measure Rn-222 concentration and determine annual effective dose of radon inhalation in the vicinity of hot springs in Kerman province, southeastern Iran. Materials and Methods: This study was carried out on 16 hot springs of Kerman province. Concentration of Rn-222 was measured using RAD-7 electronic system. Also, annual effective dose amounts of inhalation were estimated according to the formula provided by UNSCEAR (2000). Results: Minimum and maximum amounts of Rn-222 concentration in the samples were equal to 0.158±0.129 and 56.100±5.680 Bql-1, respectively. Annual effective dose amounts of inhalation were determined between 0.000±0.000 to 0.177±0.017 mSvy-1. Concentration of radon was more than 11 Bql-1 (the safe limit set by the EPA) in 5 samples collected from hot springs. Annual effective dose of inhalation of radon was more than 0.1 mSvy-1 (the safe limit set by the WHO) in Jooshan hot spring. Conclusion: By comparing concentration amounts of the samples with the EPA safe limit, it was concluded that, 11 hot springs were safe. Also, annual effective dose amounts of inhalation of all hot springs, except one of them were lower than the safe limit set by WHO.
