Exposure Analysis at the territory of Nevşehir (Cappadocia) due to additive gamma-rays in air, TURKEY

Abstract

Radioactivity measurements for water, soil, and air have been completed in national and international regions. The radioactivity process is randomized and occurs naturally by primordial nuclides. Another case is hand-made reactions which realized by artificial reactions. The high rate of the total dose of radiation, whichever is exposed to humans, originates as Natural Radioactivity. In this case, environmental radioactivity measurements are important to investigate the background radiation level, especially for primordial radioactive sources. This radiation which measured outdoor gamma dose includes both cosmic rays and terrestrial elements. Terrestrial radiation can be measured via gamma-ray spectroscopy separately. By the way, cosmic effects would be calculated by subtracting terrestrial from measured outdoor gamma dose. Scientific Committee (UNSCEAR, 2000) declares the annual dose for humans as 2.4 mSv. The radionuclides present in soil samples (terrestrial components) are considered responsible for a portion of this amount (1). Rest amounts are originated water (2) and air, too.
