An investigation on the radiological influence of an underground coal mine in Zonguldak basin, Turkey

Üzülmez underground coal mine, one of 5 collieries in Zonguldak bituminous coal basin, is located on the West Black Sea region in Turkey. The radioactivity of the terres- trial natural radionuclides 226Ra, 232Th and 40K in rock and coal samples from 17 different locations in the mine were measured by using gamma spectrometry to determine the radiological implication of the mine. The highest radioac- tivity concentrations for 226Ra, 232Th and 40K were found to be 118.8, 49.1, 561.7 Bq kg-1 and 127.7, 145.3, 1125.9 Bq kg-1, in coal and rock samples, respectively. The ra- dium equivalent activity, the internal hazard index and the annual dose equivalent associated with the radionuclides were calculated to assess the radiological hazard of natural radioactivity in the samples, and compared with the inter- national recommended values. The measured activity con- centrations were also compared with those from other coun- tries in the world. The results show that radiological effects of natural radionuclides emanated from rock and coal are negligible for this mine.
