Investigation of Natural Radioactivity of Surface Soil Samples in the Vicinity of Edirne-Turkey

Abstract

The study was carried out to determine radioactivity concentrations in surface soil samples of the city of Edirne in connection with the potential radiological hazards due to Chernobyl event. The natural radionuclide ((226)Ra, (232)Th and (40)K) contents were determined for nine different locations in nine different towns of the Edirne city. Radiation levels were measured. Natural beta-ray activity was also determined for the same locations. The average estimated activity values were determined and compared with reported values for other cities in Turkey and also for many countries of the world. The studied areas do not pose radiological risks to the inhabitants due to harmful effects of the ionizing radiation from the natural radioactivity of the soil.

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 Effect of Meteorological Parameters on Radon Concentration in Soil Gas

“…Radiometric surveys for mineral exploration or lithological mapping are routinely made from the air and on the ground [1]. The radioactivity of the soil is important since it disperses into water and air and also through the plants and other leaving beings [2]. Surveys of the radon concentration in soil gas can be used to: determine the radon index of the buildings and the effectiveness of preventive and remedial measures; identify contaminants and relative concentrations; identify sources; indicate extent of contamination [3].…”

Assessments of Natural Radioactivity Concentration and Radiological Hazard Indices in Surface Soils from the Gözlek Thermal SPA (Amasya-Turkey)

“…For this purpose, several studies have been carried out to measure the natural activity concentrations of 40 K, 226 Ra and 232 Th in different materials [3][4][5][6][7][8][9][10][11]. Natural radioactivity levels depend on the geological and geographical characteristics of the region.…”
