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 کاملNATURAL RADIOACTIVITY (Ra, Th AND K) AND ASSESSMENT OF RADIOLOGICAL HAZARDS IN THE KESTANBOL GRANITOID, TURKEY
The surveys of natural gamma-emitting radionuclides in rocks and soils from the Ezine plutonic area were conducted during 2007. Direct dose measurement using a survey meter was carried out simultaneously. The present study, which is part of the survey, analysed the activity concentrations of U, Th and K in granitoid samples from all over the region by HPGe gamma spectrometry. The activity conce...
متن کاملNatural radioactivity levels and associated radiation hazards in Nile river sediments from Aswan to El-Minia, Upper Egypt
The natural radionuclides Ra, Th and K contents in the Nile river sediments at various locations in Upper Egypt from Aswan to El-Minia have been investigated using gamma spectrometric analysis. Determination and measurement of radionuclide concentration are of great importance for assessment of external radiation dose received by man. The range and mean values of Ra, Th and K activity concentra...
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...
