Determination of the Natural Radioactivity Level of Amasya Seyhcui Region

Abstract

People are exposed to both internal and external radiation from the natural radiation sources. For this reason, studies determining the natural radiation level are made to detect the effects of radionuclides, that constitute the natural radiation sources, on the environment and especially the effects of radiation on people and on biological systems. The most common radiation sources are U-238, Ra-226, Th-232 and K-40 radioisotopes. In this study, in the samples of the rock and soil acquired from Amasya Seyhcui Region, the activity concentrations of Ra-226, Th-232 and K-40 are determined by using NaI (Tl) detector with gamma spectrometer and are compared with the limit values.
