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 کاملAssessment of natural radioactivity in various commercial tiles used for building purposes in Nigeria
In this study, we evaluated the activity concentration of natural radionuclides (226Ra, 232Th and 40K) for fifteen (15) different brands of tile samples used for building purposes in Nigeria. The tile samples were analyzed using High purity Germanium gamma detector. The mean activity concentrations of 226Ra, 232Th, and 40K were observed to be 61.1 ± 5.5 Bq/kg, 70.2 ± 6.08 Bq/kg and 514.7 ± 59.8...
متن کاملRadiological Hazard Resulting from Natural Radioactivity of Soil in East of Shazand Power Plant
Introduction: Nuclear radiation is potentially harmful to humans and soil contamination with radionuclides is the main source of human radiation exposure. These radionuclides can., enter to human body through the food chain. In this study, 34 soil samples were collected from between Arak city and Shazand Power Plant over 20 km length and analyzed. Materials and Methods: The specific activities ...
