Natural 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 Natural Radioactivity and Associated Radiation Hazards in Some Building Materials Used in Kilpenathur, Tiruvannamalai Dist, Tamilnadu, India
The present study aimed to measure the activity concentration of natural radionuclides in the locally used building materials from Kilpenthaur, Tiruvannmalai Dist, Tamilnadu, India was investigated with an aim of evaluating the radiation hazard arising due to the use of these materials in the construction of dwellings. The concentrations of natural radionuclides Ra, Th and K in four types of bu...
متن کاملNatural radioactivity concentration in raw materials used for manufacturing refractory products
Background: Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of th...
متن کاملNatural 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 کاملNatural radioactivity of some Egyptian materials used in glasses manufacturing and glass ceramics
Background: The new glasses from harmful environmental waste such as cement dust; limestone phosphate, sand and borax (Genkare) were manufactured. Investigation of the radioactivity present in these materials (Phosphate rock, cement dust, limestone, sand and borax) enables one to assess any possible radiological hazard to humankind by such materials. Materials and Methods: Fifteen samples were ...
