Environmental monitoring and urban phytodesign in ensuring the radioecological safety of urban buildings

Abstract

The purpose of this paper is to study the migration and accumulation of 90Sr in vegetative and generative organs of plants: golden currant (Ribes aureum) and cherry plum (Prunus cerasifera Ehrh). Research objectives: 1) 90SrCl2 is artificially deposited on the soil, precipitation imitation (field experiments); 2) planting plants: Prunus cerasifera Ehrh and Ribes aureum to the soil artificially contaminated with 90SrCl2; 3) cultivation and monitoring of the studied plants in the soil artificially contaminated with 90SrCl2. The contamination level of the experimental area was 500 MBq/m2. The possibilities of tree and shrub plant forms (Prunus cerasifera Ehrh; Ribes aureum) to accumulate 90Sr in their vegetative and generative organs were studied. The activity of the beta-emitting radionuclide in the counting samples was measured using the “Progress” software on the Multi-purpose spectrometric complex “Gamma Plus” device (beta path). As a result of research, the accumulation of radionuclides in both studied plants was found. In 2016, the difference in the content of 90Sr between cherry plum and golden currant in bark, wood, leaves, and fruits was 1.6, 1.5, 1.8, and 2.0 times, respectively. Experimental data can be used in the environmental monitoring of the radiation situation in urban areas of the territories allocated for the construction of public, residential buildings and structures, to be the basis for further advanced research in the designated area.
