Indoor air, building materials, raw materials. The aim of work. Measurement of gamma-dose rate, indoor radon and natural radionuclides in the environmental objects. Study methods. Analytical, radiometric, passive track radiometry method. Results. It was performed measurements of activity concentrations of Ra-226, Th-232, K-40 in 85 samples of building and raw materials, 2495 indoor measurements of equilibrium equivalent radon concentration (EERC), 11560 measurements of equivalent dose rate in buildings, 927 objects was searched in all. It was established that two types of raw materials (7 % of measured samples) due to radiation factor refer to ІІ category and can be used only for industrial or road building. It was found exceeding of the action level from 2 to 16 times in more than 55 % cases of public buildings. Dose rate at all examined objects was less than the action level in 2-3 times. It was performed methodological maintenance of work; and quality assurance due to indoor radon-222 measurements was ensured Product Description popup.authors Аксьонов Микола Васильович Лось Іван Павлович Михайленко Олександр Васильович Федоренко Олена Володимирівна Фризюк Мирослава Анатоліївна popup.nrat_date 2020-04-02 Close
