High concentrations of 226Ra (865-2,383 Bq kg-1) were measured in the coat-slags, originated from the region of the settlement Tatabanya, Transdanubian Middle Mountains, Hungary. These slags are commonly used as building materials in this district. The external gamma dose rate was measured in 188 rooms at different heights above the floor. In 124 rooms with slags used for construction, the average absorbed dose rate was 296 nGy h- 1. In 10 apartments the average radon concentration was 502 Bq m-3. In that case the estimated effective dose due to inhaled radon and its progeny and gamma radiation was 10.3 mSv y-1.
