В статье приведен обзор методик радиационного контроля содержания радона в воздухе помещений детских учреждений некоторых зарубежных стран (США, Норвегия, Финляндия), а также представлены результаты собственного комплексного радиационного обследования 9 детских учреждений в 5 населенных пунктах Ленинградской области, в которых ранее были выявлены высокие уровни объемной активности радона в воздухе помещений интегральным методом. В ходе обследования экспрессным методом в воздухе отдельных помещений были получены высокие значения эквивалентной равновесной объемной активности радона как в режиме нормальной эксплуатации зданий (до 1106 Бк/м3), так и после предварительной 12-часовой выдержки помещений при закрытых окнах и дверях согласно дверях согласно пункту 6.5 МУ 2.6.1.2838-11 (до 1586 Бк/м3). Высокие значения объемной активности радона также были получены с помощью интегральных и квазиинтегральных методов измерений (до 4900 и 1420 Бк/м3 соответственно). Кроме того, были выявлены высокие значения плотности потока радона с поверхности грунта (до 2030 мБк/(м2·с)). Ни в одном из обследованных населенных пунктов не было выявлено превышений установленных нормативов по величине мощности амбиентного эквивалента дозы гамма-излучения на открытой местности и в помещениях детских учреждений. Значения удельной суммарной альфаи бета-активности питьевой воды во всех обследованных детских учреждениях были ниже контрольных уровней, а удельной активности радона в воде – ниже уровня вмешательства. Полученные данные будут использованы для гигиенической оценки доз внутреннего облучения и радиационных рисков у обучающихся и сотрудников некоторых детских учреждений Ленинградской области за счет ингаляции изотопов радона и их короткоживущих дочерних продуктов распада и могут быть использованы для усовершенствования методики радиационного контроля содержания радона в воздухе помещений эксплуатируемых общественных зданий в Российской Федерации, что в дальнейшем позволит получать корректные значения доз облучения и радиационных рисков для здоровья населения.</p></abstract><trans-abstract xml:lang="en"><p>Currently, there is no methodological support for radiation monitoring and sanitary and epidemiological assessment of radon concentration (or radon EEC) and other parameters of the radiation situation in existing operated buildings. The paper presents a review of the protocols for conducting measurements of indoor Leningrad region with previously found elevated levels of radon concentration using long-term measurements. The survey revealed that highest values of indoor radon ECC were obtained using instant measurements in several educational institutions both in the normal operation mode of the buildings (up to 1106 Bq/m3) and after leaving the premises for 12 hours with closed windows and doors (up to 1586 Bq/m3) according to the requirements of paragraph 6.5 of MU 2.6.1.2838-11. High values of radon concentration were also obtained using long-term and short-term measurements (up to 4900 and 1420 Bq/m3, respectively). In addition, high values of radon flux density were detected (up to 2030 mBq/(m2·s)). The established hygienic norms for ambient dose equivalent rate indoors and outdoors were not exceeded in the surveyed educational institutions. The levels of gross alphaand beta activities in tap water sampled from the surveyed educational institutions were below the control levels, and an exceedance of intervention level for activity concentration of radon in analyzed samples was not detected. The results of the survey will be used for hygienic assessment of doses and health risks for students (pupils) and employees of several educational institutions of the Leningrad region due to exposure to radon and its progeny and can be used to improve the method for indoor radon concentration monitoring in existing operated public buildings in the Russian Federation, which in turn will make it possible to obtain correct values of public doses and health risks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радон</kwd><kwd>дочерние продукты распада</kwd><kwd>экспрессные измерения</kwd><kwd>интегральные измерения</kwd><kwd>квазиинтегральные измерения</kwd><kwd>общественные здания</kwd><kwd>детские учреждения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radon</kwd><kwd>progeny</kwd><kwd>instant measurements</kwd><kwd>long-term measurements</kwd><kwd>short-term measurements</kwd><kwd>public building</kwd><kwd>educational institution</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Onishchenko A., Malinovsky G., Vasilyev A., Zhukovsky M.
