Abstract |
This article describes components of the average annual contribution to total human exposure. This article presents data on specific and effective activity of natural radionuclides containing in building and raw materials for their manufacture. Here also discusses the regularities of the content of natural radionuclides (NRN) in construction materials depending on a type, origin and formation of rocks. Correlation between a look and an origin of raw materials and specific activity of NRN in construction materials is revealed. Here also considers the main use of rocks in construction industry. Specific activity of natural radionuclides — 226Ra, 232Th, 40K and effective specific activity of natural radionuclides in basic rocks is calculated. Correlation between kind and origin of raw materials and specific activity of NRN in construction materials is revealed. Possibilities of a purposeful choice of construction materials with a low content of NRN for providing safe habitat of the population are founded. |
