The present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in Ghana. Heavy metal concentrations in all samples were generally within the WHO safe limits with the average activity concentrations of 238U, 232Th, and 40K in water being respectively 0.42±0...

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 measurem...

Purpose: Radon (222Rn) and its decay products clinging to airborne particles settle in the lungs when inhaled can lead lung cancer. The main source of 222Rn is rocks soil Earth's crust causes indoor radon exposure local geological material used as a building material. Accordingly, primary objective study determine activity concentrations (CRn) exhalation rates (EA EM) from different rock types ...

BACKGROUND Present study was an attempt to measure outdoor and indoor gamma dose rates in Bushehr city to determine corresponding annual effective dose and, to assess effect of active nuclear power plant located in Bushehr city on background radiation level of this city. METHODS All measurements were performed by G.M (Geiger Muller) detector (X5C plus) calibrated in Iran Atomic Energy Agency....

background: high level radiation areas have been recognized on various parts of the earth. mahallat hot spring region is one of these areas. study of exposure in these areas can be helpful in investigating the effects of ionizing radiation. internal and external exposure to the staff was studied. materials and methods: used materials and instruments include: rss-112 ionizing chamber for environ...

a study on natural radioactivity in virgin and agricultural soil samples collected from sungai petani was conducted using high-purity germanium. the mean activity concentrations of 226ra, 232th, and 40k in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 bq kg−1, respectively. the co...
