“…Owing to the heterogeneity of source area, facial differences, varied influence of syn-depositional volcanism, the direct comparison of the uranium concentrations in coals of different ranks does not reach correct conclusions [2]. However, the relationship of uranium concentration to coal ranks and coal-forming periods represent the geochemical habit of uranium-organic affinity.…”

“…Uranium connately and ubiquitously occurs in coal. Thus, coal combustion is considered as one source of radioactive material in the environment [2][3][4][5]. Though it is controversial, the radiation doses from atmospheric emission of a coal-fired power plant were considered to be greater than those from a nuclear plant of comparable size [6,7].…”

“…It is known that coals sometimes include high contents of natural radioactive elements (U, Th, and their decay products) and, in some cases, concentrate considerable amounts of the uranium [12,13]. The four highest 40 K activity concentration are 808, 561, 561 and 541 Bq kg −1 , which were found in soil samples collected from the Soğanlıy-örük, Beycuma, İsabeyli and Alpaslan respectively.…”

“…Under the local sources we mean the private housing, where coal can be used for heating. According to [15], in coal radioactive and rare earth elements contain as impurity; these elements sorb during the burning at the fine fractions of solid particles and come to the atmospheric air. Earlier we [16] detect high concentrations of U, Th and rare earth elements in the samples from the localities of Kozhevnikovsky district.…”
