Five locations and five samples of materials from the phosphogypsum waste stack near Zgrpolci locality, in vicinity city Veles, were checked for their radon concentrations air exhalation rate. The accumulation method using AlphaGUARD DF2000 device was used specific rate determinations as well air. activity 222Rn at 5 different sampling anthropogenically introduced phosphogypsym locality ranged ...

Background: Ondo city in Ondo State Nigeria includes Ondo East and West could be described as a research city due to antecedent number of research institutes. Materials and Methods: Dose due to radioactivity content of soil samples from sixteen waste dump sites in Ondo, Southwestern Nigeria was determined using gamma-ray spectrometer in order to evaluate the radiation hazard health profile and ...

Background: A substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. Most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. Materials and Methods: Radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...

The radon area exhalation rate and mass of the soil samples collected from five different depths surface with 20 cm intervals a construction site at Kütahya, Turkey was determined by using E-Perm detectors. Accumulator method is used to determine concentration samples. Radon were measured between 34 ± 4.4 Bq.m-3 86 6.8 an average value 48.6 5.1 for days analysis time. calculated 163.7 21.3 413....
