Abstract
A significant dose contribution on the population could be derived fro m coal slags used as isolation material. Extremely high natural activi ties are measured in the coal slag, derived from the region of the set tlement Ajka, Hungary. In some buildings monitored, the elevated gamma -doses were nearly 5-10 times higher than the world average ones. The annual average indoor radon concentrations from the slag exceeded 400 Bq/m(3) and in some cases up to 1200 Bq/m(3). Due to the elevated expo sure and the radon concentrations in the dwellings the annual dose was estimated to 8-24 mSv/y more than 5-10 times of the world average one .
