“…This situation leads to an increase in the indoor radon concentration due to radon entry from the soil and low dilution by fresh air. In high-rise buildings, the air flow from the soil does not play a significant role in the radon entry on the upper floors, and the construction materials become a main source of radon [35][36][37][38] . Improving the airtightness of the high-rise multi-storey buildings can also cause depression in individual rooms and appearing additional convective air flows distributed between the building spaces.…”

“…Until present study, surveys of radon accumulation in new energy-efficient buildings in Russia were carried out only in Ekaterinburg [35][36][37][38] . As a part of these studies, a low air exchange rate in new energy efficient mid and high-rise buildings (> 9 floors), about 0.1-0.2 h −1 , and the effect of low air exchange rate on radon concentration in flats were observed.…”

During last decades, energy saving in new buildings became relevant within the energy efficiency strategies in various countries. Such energy efficient building characteristics as air tightening and low ventilation can compromise indoor air quality, in particular, increase radon concentration. In Russia, a significant part of the new buildings is the energy efficient multi-storey apartment houses. The aim of this study is to assess the significance of possible radon concentration increase in new energy efficient buildings in comparison with typical conventional multi-storey houses of previous periods. Radon surveys were conducted in Russian cities Ekaterinburg, Chelyabinsk, Saint-Petersburg and Krasnodar. The radon measurements were carried out in 478 flats using CR-39 nuclear track detectors. Energy efficiency index (EEI) was assigned to each house. All buildings were divided into six main categories. The smallest average radon concentration was observed in panel and brick houses built according to standard projects of 1970–1990 (four-city average 21 Bq/m3). The highest average radon concentration and EEI were observed in new energy efficient buildings (49 Bq/m3). The trend of radon increase in buildings ranked with high EEI index is observed in all cities. The potential increase of radiation exposure in energy-efficient buildings should be analyzed taking into account the principles of radiological protection.

“…When inhaling vapors of radioactive gases, as well as dust particles with radionuclides sorbed on their surface, the epithelium of the nasopharyngeal mucosa, trachea, bronchi, alveoli are irradiated with alpha particles, which causes microburns of tissues and can lead to the development of lung cancer. At the same time, more than 95% of the human radiation dose is caused by inhalation not of radon itself, but of its short-lived daughter decay products -isotopes 210Po, 214Bi and 214Pb [1,2,4,5].…”

The levels of natural background radiation in certain territories of the Russian Federation differ significantly from each other and can vary widely. Most of the population receives radiation doses from natural sources of ionizing radiation from 2 to 4 mSv/year, but in some areas their radiation levels exceed 10 mSv/year. The population of the Russian Federation receives the main collective dose of radiation from natural radiation while living and working in enclosed residential, public and industrial buildings. In them, the levels of ionizing radiation in buildings, as a rule, depend on the level of the radiation background of the territory, which is determined by the geological, geochemical features of the area and its terrain, as well as on the type of building, radioactivity of the building materials used, emanation and exhalation of radon and daughter products of its decay into rooms from the ground and building materials used. The average annual individual doses of ionizing radiation in buildings, with the exception of certain territories, are small, but they can in isolated cases cause somatic and genetic effects in humans. To reduce the likelihood of such consequences in the Russian Federation, a system of legal and organizational provision of radiation safety of the population during the construction and reconstruction of buildings was developed, environmental and hygienic requirements for it were determined.

An application of geometric mixed additive-multiplicative models for lung cancer risk modeling under combined action of radon and smoking is justified in this paper. The geometric mixed model allows: 1) to reduce the discrepancies between estimates of the lung cancer risk for males and females, 2) to predict the population risk under condition of the varying smoking prevalence and changing average indoor radon concentration level. Using the geometric mixed model, the calculation of the lung cancer risks for the Russian Federation population was carried out for different percentages of smokers among the population, an increase in life expectancy, and a change in the average radon concentration level in residential buildings. Assuming that currently rounded average indoor radon concentration in Russia is 50 Bq/m3, the contribution of radon to total mortality in 2009 was 0.46% and 0.20% for male and female, respectively. Modeling has shown that the effect of lung cancer mortality reducing due to the predicted decrease in the proportion of smoking population will partly be offset by an increase in the realization of lung cancer risk with the life expectancy increase. For a hypothetical situation, when the entire population maintain a healthy lifestyle and mortality from cardiovascular, oncological, infectious diseases, diseases of the respiratory tract and from external causes has significantly decreased, the contribution of radon exposure to total mortality will increase to about 0.8%. If the average level of radon in buildings will increase due to energy-efficient technologies widespread implementation in building construction, the contribution of radon to total mortality will be even more noticeable.
