Regularities of Radon Accumulation in Premises of Buildings and Structures

A person receives most of the annual radiation dose from radon and its daughter products of decay due to prolonged stay in the premises. Therefore, the main task of ensuring radiation safety of the population is to find ways to reduce this value. Engineers in Russia and abroad have questions about why the activity of radon-222 is stable in certain areas of buildings and structures, while in others, on the contrary, it increases or decreases. It is clear that these phenomena reflect the action of some unknown laws. But which ones? In this paper, the author uses concrete examples to show the results of research on these regularities. It is established that to replace the decayed radon atoms, that insignificant amount of radon-222, which comes from the internal surfaces of buildings and structures, is enough with excess. The article is a continuation of the previously started research.
