natural radioactivity of granites used as building materials in iran
the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...
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...
متن کاملFirst characterisation of natural radioactivity in building materials manufactured in Albania.
This study focuses on the radiological characterisation of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of (40)K, (226)Ra and (232)Th were, respectively, 644.1±64.2, 33.4 ± 6.4 and 42.2 ± 7.6 Bq kg(-1) in the clay brick samples and 179.7 ± 48.9, 55.0 ± 5.8 and 17.0 ± 3.3 Bq kg(-1) in the cement samples. The cal...
متن کاملReview of international normatives for natural radioactivity determination in building materials
Natural radioactivity is the main source of radiation which affects the human body [1]. Anthropogenic activities (e.g. high-altitude fl ights, mining and living in buildings) have increased the exposure to these sources [2]. In particular, the problem of natural radioactivity in buildings is of great interest since the building materials are of terrestrial origin and they consequently contain s...
متن کاملExposure to radiation from the natural radioactivity in Jordanian building materials.
The natural radioactivity due to the presence of (226)Ra, (232)Th and (40)K in selected building materials used in Jordanian building constructions has been measured using gamma-ray spectrometer with a Hyper Pure germanium detector. The average activity concentrations observed in different building materials ranged from 27.7 +/- 7.5 to 70.4 +/- 2.8, 5.9 +/- 0.67 to 32.9 +/- 3.9 and 30.8 +/- 0.8...
