- Abstract
The naturally occurring radionuclide (Ra,Th andK) content of building Materials (NORM) contributes to the total radiation dose experienced by humans. In this survey 27 clay and 68 red mud samples were surveyed with gamma spectrometry and screened according to European Basic Safety Standards (BSS) I-index. It was found that average I-index of clays was 0.6 (0.4-0.8) less than the I-index of 1, which makes them suitable for building material production. The average I-index of red mud 2.3 (1.3-3.0). The maximal mixing ratio of red mud was calculated, varied between 12 and 39 %, with 23 % average.
