Abstract
The objective of this paper is the valuation of radiological health effects of Yatagan Power Plant. To this aim the radiation dose calculations are carried out for the population living within 80 km radius of the plant. The average of the maximum measured specific isotopes 238U, 232Th and 226Ra in the flying ash samples are considered as radioactive sources. Based on the dose calculations, first the stochastic health effects and then monetary health effects are estimated. The estimated total collective dose and economic value of the pre-dicted health effects are 0.3098 man Sv/y and 14791 US$/y respectively. The results obtained from the dose calculations are lower than the limits of International Commission of Radiation Protection (ICRP) and it does not pose any risk for public health. Monetary value of health risks is also negligible in comparison to the av-erage yearly sales revenue of the plant which is 250 million US$.

Summary
Yatağan Power Plant (YPP) is one of the largest lignitefired power plants in Turkey with a total capacity of 630 MW It has been operated in Muğla province at the western Anatolia since 1982 [1]. The radiation dose calculations have been carried out using the code CAP88-PC which stands for Clean Air Act Assessment Package [6] for the population living within 80 km radius of the YPP by using the average of the maximum measured specific isotopes 238U, 232Th and 226Ra in the flying ash samples as radioactive sources. Annual radioactivity release rate for three different radionuclides in the dose calculations is calculated by using the ash emission rate from the plant chimney, the measured activity in flying ash and the plant loading factor [11,12].
