Determination of the Natural Radioactivity Level of Amasya Şeyhcui 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 238 U, 226 Ra, 232 Th and 40 K radioisotopes. In this study, in the samples of the rock and soil acquired from Amasya Şeyhcui Region, the activity concentrations of 226 Ra, 232 Th and 40 K are determined by using NaI (Tl) detector with gamma spectrometer and are compared with the limit values.

K-Ar Dating for Determining the Age of Mineralization as Alteration Product: A Case Study of Antimony Mineralization Vein Type in Granitic Rocks of Gümüşhane Area, Turkey

“…Potassium is chemically incorporated into common minerals, especially in hornblende, biotite and potassium feldspar, which are component minerals of igneous rocks, and in muscovite, sericite, illite, which are component minerals of hydrothermally altered products [6][7][8][9][10]. Since argon is an inert gas, it cannot combine chemically with anything, so just after minerals have formed there is not much argon in igneous rocks.…”

The Investigation of Radionuclide Concentrations in Soil and Lifetime Cancer Risk Due to Gamma Radioactivity in Zonguldak, Turkey

“…The terrestrial component of the natural background radiation depends on the compositions of soil and rocks containing natural and artificial radionuclides [1,2]. An important contribution to total dose from natural sources comes from terrestrial radionuclides, such as 238 U, 232 Th and 40 K, existing in soil [3,4]. Since these radionuclides are not uniformly distributed, the knowledge of their distribution in soil and rocks, due to the difference in the geological structure of the region, plays an important role in radiation protection and measurement.…”

Radioactivity Investigation of Sediment Samples from Beni Haroun Dam Using High-Resolution Gamma-Ray Spectroscopy

“…In order to obtain the information about the present levels of environmental radioactivity, various studies were carried out in many countries [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In the current work, sediment samples were collected near Beni Haroun Dam.…”
