Variations of Rn concentrations over active fault system in Simav, Kütahya, Western Turkey: Possible causes for soil-gas Rn anomalies.

Soil-gas Rn concentrations were investigated on an active Simav Graben/Fault System in Western Turkey. Measurements to understand the causes of variations in soil-gas Rn were conducted in three distinct sections such that seven selected measurement points in each section lie on a line that is approximately perpendicular to the main fault line. It was found out in each section that values obtained at two adjacent points were abnormally higher than the rest.

RADIOACTIVITY CONTENT OF BUILDING MATERIALS USED IN KUTAHYA PROVINCE, TURKEY.

Radioactivity concentrations of primordial radionuclides Ra-226, Th-232 and K-40 for 31 samples of seven different types of construction materials used in Kütahya Province, Turkey, were analyzed using NaI(Tl) gamma spectroscopy. Ra-226, Th-232 and K-40 activities of all samples ranged between <2.0 and 81.

Assessment of radiological hazard parameters due to natural radioactivity in soils from granite-rich regions in Kütahya Province, Turkey.

The analysis of natural radioactivity from U, Th and K in 357 soil samples collected from the province of Kütahya was carried out using a NaI(Tl) gamma-ray spectroscopy system at the Nuclear Physics Research Laboratory, Dumlupınar University, Kütahya, Turkey. The specific activities of U, Th and K in the soil samples were evaluated. From the activity concentrations of U, Th and K, the total absorbed outdoor gamma-ray dose rates and the corresponding annual effective dose rates were determined.
