“…Besides the natural radiation sources, anthropogenic activities such as mining operations, the use of phosphate fertilizers and burning of fossil fuels have been a continuous subject of concern. Particularly, a number of publications have been concerned with the radioactivity levels of the airborne discharges from coal-fired power plants (Papastefanou and Charalambous, 1979;Tadmor, 1986;Papastefanou, 1996;Kljajić et al, 1996;Lokobauer et al, 1997;Yaprak, 1999;Rouni et al, 2001;Flues et al, 2002;Bem et al, 2002;Papaefthymiou et al, 2005;Zeevaert et al, 2006). The high natural content of radionuclides in coal, especially in lignite, and the pollution control devices at power plants are responsible for the contamination of the area in the vicinity of these facilities (Swaine, 1990;Clark and Sloss, 1992).…”
