Использование: трековый контроль радиоактивности, в частности радона, в окружающей среде. Сущность изобретения: способ заключается в отборе фиксированного объема воздуха в сосуд и измерения в нем радиоактивности радона и его дочерних продуктов, причем вблизи детектора между стенками сосуда и детектором создают разность температур и конвекционные токи, переносящие радон и его дочерние продукты к чувствительной поверхности детектора.Usage: track control of radioactivity, in particular radon, in the environment. The inventive method consists in taking a fixed volume of air into a vessel and measuring in it the radioactivity of radon and its daughter products, and near the detector between the walls of the vessel and the detector create a temperature difference and convection currents transferring radon and its daughter products to the sensitive surface of the detector.
