natural 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 the na...
متن کاملNatural radioactivity concentration in raw materials used for manufacturing refractory products
Many materials that are usually found in the earth's crust contain small but measurable amount of naturally occurring radioactivity (NORM). Some particular ores contain natural radionuclide at levels much higher those usually present in earth's crust; and are also subject to radioisotope enrichment, during technological process, known as technologically enhanced natural radioactivity (TENORM). ...
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 ...
متن کاملNatural radioactivity in raw materials used in building industry in Serbia
Natural radioactivity is responsible for most of the total radiation dose received by human population. Geological materials used in building industry usually become contaminated with naturally occurring radioactive materials. They are used as mixtures in building industry (kaolin, zircon, frit, feldspar) or mechanically processed and used for covering floors and walls of the rooms (granite). I...
