Description

A total of 36 samples of Brazilian raw materials and building products were analysed by high resolution gamma spectrometry for their 226 Ra, 232 Th and 40 K content. The effective dose equivalent rate due to the indoor gamma radiation from those materials was performed following the 1988 UNSCEAR procedures. The values obtained ranged from 4.0 x 10-3 mSv/y (concrete beam) to 0.3 mSv/y (concrete) which are below the 0.8 mSv/y assumed UNSCEAR value for natural radiation sources. (author). 14 refs., 2 tabs
