Малоинтенсивные радиоактивные аномалии на территории города Архангельска

Малоинтенсивные радиоактивные аномалии на территории города Архангельска

Abstract

Цель данной работы выявить на территории города Архангельска основные малоинтенсивные радиоактивные аномалии как основной вероятный источник облучения людей малыми дозами; дать объективную оценку радиационных рисков и потенциального ущерба здоровью местного населения. Впервые на территории города применен метод автогамма-спектрометрической съемки с использованием мобильной системы радиационного мониторинга RS-700, которая позволяет измерять как природные, так и искусственные радионуклиды в реальном времени с точной привязкой к местности. Для детализации полученных результатов был применен метод пешеходной гамма-съемки с использованием геологоразведочного сцинтилляционного радиометра СРП-88Н и проведен почвенный отбор проб в каждом квартале города с дальнейшим определением удельной активности радионуклидов в счетном образце на гамма-спектрометре «Прогресс». В ходе радиоэкологического исследования получен уникальный массив данных по радиоактивному фону и удельной активности 137Cs, 40K, 232Th, 226Ra в почвах. Выявлено девять локальных малоинтенсивных аномалий, определен их генезис. Сделана сравнительная комплексная оценка воздействия малых доз ионизирующей радиации на здоровье населения. Намечены возможные пути проведения дальнейших медико-экологических исследований в области изучения связи онкологических заболеваний и радиоактивности на территории Архангельска.

The goal of the research is to find out the main low-intensity radioactive anomalies as the main probable source of human light irradiation in Arkhangelsk city; give an objective estimation of radiation risks and potential health damage of the local population. Avtogamma-spectrometric method, using a mobile radiation monitoring system RS-700 was firstly used in the city. It allows to measure both natural and artificial radionuclides in real time geo-referenced. Ground gamma survey method with geological prospecting scintillation radiometer SRP-88H has been used for specification of obtained results. Soil sampling has been selected in each city block with further definition of radionuclides specific activity in the gamma spectrometer counting sample "Progress". A unique set of data on the radioactive level and the specific activity of 137Cs, 40K, 232Th, 226Ra in the soil have been collected as a part of the radio-ecological study. Nine local low-intensity anomalies have been revealed and their genesis has been set. The comparative comprehensive assessment of low doses ionizing radiation on human health has been done. Possible ways of further medical and environmental research in the field of oncological diseases and radioactivity study in the city of Arkhangelsk have been planned.
