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 کاملAssessment of the natural radioactivity and its radiological hazards in some Egyptian rock phosphates
Radioactivity of terrestrial radionuclides Ra, Th and K in phosphate rock samples has been measured using gamma ray spectrometry system with an HPGe detector. The samples showed fairly high mean concentrations, 410±39 Bq.kg of Ra, 7.9±0.95 of Th and 37.6±4 of K. Mean absorbed gamma dose rate of 181.9±20 nGy.h was measured in air. Assessment of radiological hazards was made by calculating radium...
متن کاملStudy of natural radioactivity to Assess of radiation hazards from soil samples collected from Mounana in south-east of Gabon
Background: The present work aims to determine the activity concentrations of 226Ra, 233Th and 40K in soil samples collected in Mounana in the Southeastern region of Gabon, to evaluate the contribution of the natural. Materials and Methods: An HPGe p-type detector coupled with a multichannel analyzer DSA-1000 was used to perform measurements and process data. Data acquisition and analysis were ...
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 کاملMeasurement of Natural Radioactivity and Assessment of Associated Radiation Hazards in Soil Samples
Introduction e knowledge of radionuclide distribution and radiation levels in the environment is important for assessing the effects of radiation exposure due to both terrestrial and cosmogenic sources. Terrestrial radiation is due to radioactive nuclides present in varying amounts in soils, building materials, water, rocks and atmosphere. Some of the radionuclides from these sources are trans...
