measuring the artificial radionuclide concentrations in the water and sediment samples of arvandrood

background: due to the evacuation of some industrial wastewaters to arvandrood, the presence of the radionuclide material in the river is likely. the purpose of this study was to determine the radioactivity rate in arvandrood land area to the persian gulf. methods: : the concentration of cesium radionuclide (cs137) was measured in 20 sediment samples and 8 water samples which were collected from 20 and 8 different stations in arvandrood respectively. the radionuclide radioactivity rates in the sediment samples were measured by using gamma spectrometry. the data were analyzed by spss and anova. findings: the artificial radionuclide cesium 137 radioactivity levels in sediment samples were achieved in the range of 1.13 to 4.16bq.kg-1. conclusion: the concentrations obtained in water samples were counted lower than the mda system. there is not any threat to human health in terms of radionuclide presence in arvandrood key words: gamma-spectrometry, arvandrood, cesium-137, artificial radionuclide
