Research of regulated radiation parameters on the residential peremoha-6, Dnipro

The radioactivity of building materials and products is determined by the content of natural radionuclides (NRN) of the three dominant chemical elements (238U, 232Th, 40К) in the structural elements of buildings. It is these radionuclides that determine the total dose of human exposure in our homes. The main building structures that were used to build up many of the sleeping areas of the Dnepr are heavy concrete, and accounted for 70…85 % of the total production of the construction industry of the region. Over the past 20 years, trends in construction production, both in Ukraine and in the Dnepr city, have been revised. Modern construction organizations are trying to build at least 16 floors using the so-called monolithic frame construction with filling holes from cellular concrete and subsequent insulation or facing of facades. One of the most numerous in terms of the number of inhabitants is the Peremoga housing estate and in particular the Peremoga-6 railway station, where you can find civil, public, office, administrative buildings of different years of construction. The problem is urgent, as it is aimed at determining the actual state of things in the field of radiation safety of construction sites of Peremoha-6 railway station in operation. Purpose of the article. Systematic radiation surveys of buildings and structures of the housing stock based on studies of the real level of radiation background of residential buildings in operation. Conclusion. As a result of experimental studies and calculation of the values of Nef.vneshn and Nef.vn, it was found that the values of regulated radiation parameters generated from sources of ionizing radiation of technogenic origin and the general radiation background that they create in the premises of buildings of Peremoha-6 railway station exceed indicators for category B, which in turn requires a decrease in the value of Nef.Σ, based on the implementation of architectural, planning and technical anti-radiation protective measures.
