Background: Salivary flow rate (SFR), to estimate salivary gland dysfunction and radioactivity in different body fluids, to evaluate its intensity, were determined in thyroid patients after 131-I therapy. Material and Methods: For determination of SFR an innovative sponge test was adopted and the radioactivity in saliva, blood and serum of thyroid patients was determined by NaI (TI) Scintillati...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...
