Assessment of natural radioactivity levels for Karadağ Mountain, Turkey (original) (raw)

Background:The natural radioac vity levels in soil samples of Karadağ Mountain in central Anatolia region have been determined. Materials and Methods: Analyses on the collected samples were performed to determine gross alpha and beta radioac vity concentra ons by using a gas-flow propor onal counter and the concentra ons of U, Th and K by using a NaI(Tl) scin lla on detector. Results: The es mated ac vi es of gross alpha and beta ranged between 305.155±46.830 and 1305.437±77.23 Bq.kg-1, 479.743±22.658 and 1177.373±30.908 Bq.kg-1, respec vely. The mean ac vity values of U, Th and K radionuclides were found to be 71.6, 83.9 and 451.1 Bq.kg-1, respec vely. Also, known radia on health hazard indices were calculated using radioac vity concentra ons of soil samples. Conclusion: The present results have been compared with the obtained values from other regions in Turkey and the interna onally reported values as well as the reference values. The soil samples in the studied area are safe and...
