Geoecological assessment methods of the radiation hazard of the use of rocks in the building materials industry

Abstract

The production of human activity has led to the formation of technogenic radiation background, which is formed in its habitat due to initially distributed in the structures of the earth, particularly in rocks, “eternal” natural radionuclides (NRN). In its turn, rocks are the main raw material for building materials and products from them. Natural radionuclides are a source of radiation hazard to humans and their habitats throughout the entire chain of production and use of building materials for the construction of residential, administrative and industrial buildings. In order to reduce the factors of the negative impact of man-made radiation background on a person it is possible on the basis of studies of the radiation characteristics of building materials and raw materials for their manufacture, to identify sources of NRN in the chain from rocks to industrial production. In turn, the completeness and validity of the results is possible only on the basis of a comprehensive geo-environmental assessment of the radiation hazard characteristics of building materials and raw materials for their manufacture, which will reduce the negative impact on the ecology of the human environment through the use of “radiation-friendly” materials.
