Abstract
The radiological impact of a flue gas purification system in a coal fired power plant was evaluated. It was seen that the naturally occurring radioactive materials concentrate in the fly ash by a factor 7 to 9, and in the bottom ash by a factor 4 to 5, as could be expected, but due to the low radioactivity contents of the utilized coal, this does not pose any problem from a radiation protection point of view. The gypsum produced during the wet scrubbing procedure with lime in the DESOX installation showed no increased natural radioactivity concentrations and is radiologically comparable to natural gypsum. The overall radiological impact of the flue gas purification system is negligible to the plant workers and to the general public, and the by-products such as fly ash, bottom ash and gypsum can safely be used in building materials without problems from the point of view of radiation protection.
