background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident.  rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...

wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...

In the last few years, tendency to utilization of bottled water has significantly expanded. Therefore, its radioactivity level must be strictly evaluated. This work aims measure activity concentrations gross beta and alpha in drinking evaluate quality annual effective dose as well lifetime risk. The 30 mineral samples from several brands was analyzed with Wallac Quantulus 1220 LSC. measurement ...

background: the use of chemicals is essential in education resulting in exposure to these pollutant in a variety of chemical and research laboratories. chemical contaminants in chemical laboratories are in different forms and chemical exposure risk assessment is important for choosing appropriate controls in protecting the health of operators, experts and students. for risk assessment in chemic...

Human activities such as waste disposal tend to impact negatively on the environment. Some products are associated with elevated levels of natural radioactivity. It was therefore, aim study investigate health risk radioactivity from Okakarara municipal dumpsite. In this study, gamma spectrometric analysis used determine activity concentrations 226Ra, 232Th and 40K in 18 soil samples. From these...
