Studies of radon activity in civil engineering and environmental objects

Abstract

In this article, studies of the radiation (radon) characteristics of the soil, soil-forming rocks and civil engineering buildings of the Volgograd Region are presented. The purpose of the study was to identify factors of the radiation background caused by radon in civil engineering objects. The regularities of radon distribution at the objects of the construction complex and the environment are determined depending on the influence of various factors. The studies made it possible to calculate the averaged annual effective equivalent doses to the population of the Volgograd Region caused by radon and the daughter products of the decay of radon. As a result, the patterns of changes in radon activity in the air of the premises have been established, depending on the time of the year, building materials and the purpose of the room. The result of the work performed is the normative material for use in the construction industry in order to limit the radiation exposure of the population in the region. Also, methodological material for training specialists in the field of radiation research in the building complex.

The Raw Building Materials’ Research Quantitative Characteristics Radioactivity in Volgograd Region

“…It should be noted that all materials studied correspond to class I materials on radioactivity and can be used for the production of building materials and for all types of construction without restriction [8,12,21].…”

“…It was taken stepwise or Gaussian. The best result was shown by the variant in which the initial initialization of the map was carried out from eigenvectors, and the neighborhood function was assumed to be Gaussian [8,19].…”

“…for each object find the class to which it belongs. As a result of obtaining new information about classes, it is possible to correct the existing rules for the classification of objects [8].…”

Distribution of 222Rn decay products in a soil sample

“…The results are meant to be used for metrology purposes and cross-disciplinary applications, including geoecology [4] and urban healthcare (civil to industrial purposes [5], including underground parking facilities). Additionally, radon migration is a very complex issue, as depicted in the work of Gilmore et al [6].…”
