Nowadays, the proposed standard for determination of building material ACI is a laboratory analyses technique. In this paper, the B-NORM method for determination of building material ACI is assessed as a faster method that can be performed on-site. The B-NORM method utilizes a LaBr3(Ce) scintillation probe to obtain the spectral data. The ACI was determined by interpreting the gamma spectrum from 226Ra and its progeny; 232Th progeny and 40K. In order to assess the accuracy of the B-NORM method, a large selection of samples was analyzed by a certified laboratory and the results were compared with the B-NORM results. The results obtained with the B-NORM method were in good correlation with the results obtained by the certified laboratory. The B-NORM method was applied to analyze more than 120 building materials.
