Abstract:
The results of determination of natural radionuclides (226Ra, 232Th, 40K)
in raw building materials and final products are presented. Activity of the radionuclides was
determined on an HPGe detector by standard gamma spectrometry. Mean activities of natural
radionuclides were in the range of 2.0-560 Bq/kg depending on the radionuclide and the type of the
material. Equivalent indices and OECD index for natural radionuclides were calculated, indicating
lower content of natural radionuclides compared with data from other European countries. Indoor
radon concentrations were measured in Belgrade dwellings by alpha scintillation counting technique.
The concentrations were under 200 Bq/m3, depending on geochemical characteristics of the soil,
building materials, construction of the building, storey number, dwelling conditions, as well as
on the season. The measurements were performed as a part of the Quality Control Program for the
Assessment by a National Laboratory for Radioactivity Control of Building Materials.
