The biological effects of natural radionuclides from the construction materials on the population of the volgograd region

The paper presents the study of the effect of radiation dose due to gamma background from construction materials in the Volgograd region on the exposure of the population and the identification of possible impacts. Methods to protect the population from the effects of natural radionuclides are suggested. Direct studies have established the absorbed dose rate of the Volgograd region inside wooden, brick and concrete buildings in Volgograd region. The analysis of the frequency distribution of the effective specific activity of natural radionuclides in building materials was conducted. It was found that the population of the Volgograd region is exposed to more radiation from building materials than in Russia on average. It is found that the dose received by the human body over a long period, results in a more serious injury than the same dose received in a short period.
