Popis: The natural radiation background is an important abiotic factor. Nowadays, radiation from natural sources is enhanced by a man-made component. Population growth stimulates construction, for which natural mineral raw materials are used. Uranium and its daughter radionuclides contained in building materials increase the impact of natural sources of radiation on humans. Radon is the main dose-forming radionuclide. Its measurement is a difficult task. Among the products of radon fission are gamma emitters, which, together with other natural radionuclides, form the radiation background of residential premises. The paper analyzes the features of the formation of the power of the ambient dose equivalent of gamma radiation in the air of residential buildings in the city of Zhytomyr. It has been established that the power level of the equivalent dose in residential premises depends on the height of the building and the type of building materials. It was found that the highest level of gamma background is recorded on the first floors of panel buildings. It was 16 % higher than on the first floors of brick buildings, 20 % higher than on the second and 25 % higher than on the third floors of panel houses. The difference is statistically significant. It is also shown that there is a trend towards an increase in the gamma background in more modern buildings compared to older ones.
