Natural radioactivity in ceramic tiles and associated radiological hazards
Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...
متن کاملComparative assessment of natural radioactivity and radiological hazards in building tiles and sharp sand sourced locally and those imported from China and India
Background: Thirteen (13) types of building tiles and Sharp sand commonly used for building purposes were collected for their radionuclide contents analysis. Both imported and locally produced building tiles were examined. Materials and Methods: The samples of tiles and sand were crushed to powder and they were prepared such that their content could be examined by the use of gamma-ray spectrom...
متن کاملRadiological hazards assessment of laterite mining field in Ilorin, North-central Nigeria
Background: Assessment of activity concentrations of 238U, 232Th, 40K and gamma dose rate (DR) was carried out over a laterite mining field in Ilorin-south, Nigeria. Materials and Methods: A well calibrated Super-Spec (RS-125) gamma spectrometer was used to measure the activity concentrations of 40K, 238U, 232Th and gamma doses rate at 1 m above the ground level over the laterite mining field. ...
متن کاملRadiological risk analysis of sediment from Kutubdia island, Bangladesh due to natural and anthropogenic radionuclides
To assess the environmental radioactivity levels and hence to determine the population exposure in Kutubdia Island, Bangladesh the sediment samples were analyzed by using gamma ray spectrometry. In those sediment samples the average activity concentration of natural radionuclides 238U, 232Th and 40K were found 15.39±1.67, 38.35±0.76 and 475.51±21.15 Bq/kg respectively. ...
متن کاملCorrelation of gamma emitting radionuclides and radiological health hazards indices around Lancaster dam
Background: All human beings and living organisms are exposed to natural radiations on daily basis, which is mainly due to the activity concentration of primordial radionuclides 232Th, 238U and their products of decay together with the natural radionuclide 40K present in the earth’s crust. Materials and Methods: A total of 59 soil samples were collected around the banks and surroundings of the ...
