introduction foodstuffs are known to contain natural and artificial radionuclides. determination of radionuclide concentration is of great significance for the protection of human health. the main objective of the present study was the quantification of radionuclides in tea samples, cultivated in guilan province in north of iran. materials and methods the activity concentrations of 226ra, 232th...

this study was conducted to determine the radioactivity concentration in soil samples of anarak-khour district located at central iran. 48 soil samples from a depth of 10-15 cm were taken from seven different sites for monitoring. the radioactivity concentration of 238u, 232th, 137cs and 40k in soil samples was determined, using a high resolution (hpge detector, p-type) γ-spectrometry by detect...

abstractbackground : the presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations.   materials and methods: a total of 56 samples from 18 different foodstuff ...

natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...

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...

natural background radiation is the main source of human exposure to radioactive material. soils naturally have radioactive mineral contents. the aim of this study is to determine natural ((238) u, (232) th, (40) k) and artificial ((137) cs) radioactivity levels in wheat and corn fields of eilam province.hpge detector was used to measure the concentration activity of (238) u and (232) th series...
