【 摘 要 】

The concept of safety and assurance of vital human activities in urbanization is one of the most significant backbone concepts of human ecology. The comfort of residential buildings under construction is largely owed to the radiation properties of the construction materials used. Therefore, the radiation-related hygienic support of technological processes and construction is an important issue for the construction industry. The paper considers the regularities of the formation of indoor background gamma radiation depending on various factors, in particular on the impact of the specific activities of naturally occurring radionuclides in construction materials. The results of the investigation allowed determining that the annual accumulated dose calculated according to the formula and the actual accumulated dose in buildings constructed of various materials comply with the normative documents, however the accumulated doses of human exposure in panel buildings are 4-6 times higher than in other types of buildings.
