Effect of Thermal Treatment of Building Materials on Natural Radionuclides Effective Specific Activity

Article Preview

Abstract:

The influence of heat treatment (burning) of building materials on the effective specific activity of natural radionuclides was investigated. Analysis and processing of the obtained results allowed to obtain a consistent pattern of this process for each material. It has been established that the effective specific activity of natural radionuclides decreases along with growth of temperature of building rocks treatment. The results showed that it is possible to reduce the effective specific activity of natural radionuclides managing technological production modes and, consequently, to reduce the radiation doses of the population from these materials.
