Investigation of the activity of natural radionuclides in the building materials

What is it about?

The analysis of frequency distribution of effective specific activity of natural radionuclides in construction materials was carried out. It was revealed that the population of the Volgograd region is more exposed to radiation from construction materials, than on average across Russia. The radiation control while developing and marketing of construction materials to is a possible way to decrease a dosage power in premises.

Why is it important?

In the course of this study, the problem was solved, which has significant practical value - reducing dose loads from natural radionuclides contained in construction materials in residential and public buildings. For the first time extensive radiological studies (more than 7000 measurements) of residential, public and industrial buildings, built from a variety of building materials has been conducted in the Volgograd region. It was established that the ADR in production facilities of construction companies is an average of 15 - 20% higher than in residential areas. The regularities of changes in territorial dose power, as well as dose power for deposits of building materials and premises, depending on the influence of various factors (time of year, the building materials used, the number of storeys of the building, etc.) were revealed. The map of radiation dose distribution was made up for the first time in Volgograd region, allowing engineer design organizations to navigate during radiation-ecological survey and designated areas for development.
