- In the present study, the activity concentrations of 226Ra, 232Th, 40K in some building and raw materials used in Croatia were measured by using a gamma-ray spectrometer with the HPGe detector. The average activity concentrations of the studied different building and raw materials ranged from 11.6 š 1.7 (concrete) to 251.2 š 25.7 Bqkg-1 (GBFS), 14.0 š 2.7 (concrete) to 54.4 š 8.3 (coal fly ash) and 147.2 š 19.0 (concrete) to 773.7 š 82.0 Bqkg-1 (tuff) for 226Ra, 232Th and 40K, respectively. Radium equivalent activity, activity concentration index, absorbed gamma dose rate indoor due to the external exposure and corresponding annual effective dose were determined to estimate the exposure risk arising due to the use of these building and raw materials.
