| Abstract: | This preliminary study presents the experimental results concerning the concentrations of selected radionuclides (238U, 232K, 226Ra, 232Th) in Af?in-Elbistan, Çan, Çay?rhan, Erzurum, Göynük, Kangal, Orhaneli, Saray, Seyitömer, Soma, Tunçbilek, Yata?an and Yeniköy lignites, which are primarily utilized as fuel for thermal power plants in Turkey. Gamma-spectrometry of 39 representative lignite samples gave results with the following concentration ranges: 8 to 296 Bq/kg for 238U, 3 to 79 Bq/kg for 232Th, 17 to 360 Bq/kg for 40K, and 5 to 130 Bq/kg for 226Ra. The 238U results reported here are higher than other literature values for various world coals, earth's crust and world average. |
