Контроль содержания радона в зданиях проводится уже несколько десятилетий во многих странах мира, включая Россию. Однако до сих пор результаты контроля радона в помещениях нельзя считать надежными, поскольку сложившаяся практика не предусматривает количественную оценку неопределенности среднегодовой объемной активности (СОА) радона, как и его среднегодовой экви-валентной равновесной объемной активности (СЭА). Эта проблема достаточно подробно рассматривается в первой части статьи [1] (далее -Часть 1). Кроме того, в Части 1 представлен принцип, обеспечивающий надежность контроля радона в помещениях, поскольку он соответствует требованиям метрологии и современных стандартов. Этот принцип вводит новый параметр -коэффициент K V (t), который выражает неопределенность временных вариаций

This paper reports the results of a study which explores the rate of indoor radon content in four settlements of Chebarkul district in Chelyabinsk region, Russia. A large number of heterogeneous rock formation areas with inclusions of thorium and uranium mineralization is a distinguishing feature of Chelyabinsk region. The natural γ-background in the study area is 110 mSv⋅h−1. The study provides the obtained results of radon content in winter, spring, summer and autumn in rooms in buildings made of wood, brick, concrete panels. Y-background and equivalent equilibrium volume activity were measured in open areas and in premises with ergonometric PAA-10 and “Alpha Guard 2000”. The average annual equivalent equilibrium volume activity of radon for all buildings varied greatly depending on the materials used for construction (from 21.5±2.2 to 176.2±15.6 Bq⋅m−3). The highest values were recorded for the premises made of wood. According to the indoor radon content in the premises made of different building materials, the studied settlements were classified into several categories of being radon hazardous (the first, second and third). The range of annual average values of equivalent equilibrium volume activity in different premises was identified in the reducing order which is the following: winter - autumn - spring - summer. The differences of the mean radon content in different seasons were statistically significant. Conservative estimates of annual doses of radon in all the studied premises ranged from 120 mSv⋅year−1 to 195 mSv⋅year−1, depending on the type of construction.

Full-scale investigations have demonstrated that radon contained in soil air provides dominant influence on the university’s radon field formation. The change of radon volume activity in the university’s civil defense hideout and premises have strongly pronounced seasonal pattern with maximum values of radon concentration in July and August, and minimum values in March, April and November. Radon escaping from the soil surface in the summertime does not affect the radon field change in the university’s premises. The most precise estimation of radon annual average volume activity can be obtained when performing observations during a year. The substitution of this approach by the method of measurements with various duration leads to errors in the estimation of the normative parameter because of difficulties in registration of radon variations in various conditions.
