Laboratory of Radioecology


The Laboratory of Radioecology is engaged in research of behavior of natural and man-made radioisotopes in natural and agricultural ecosystems. The main tasks of the laboratory are the analysis of migration Chernobyl-released radionuclides and their transfer in food chains, the assessing exposure to ionizing radiation biota and humans, as well as the development of methods for reducing the bioavailability of pollutants and remediation of territories disturbed by industrial activity.

The Laboratory of Radioecology is developing combined biologically active soil-improving additives for the rehabilitation of contaminated and disturbed soils, as well as improving the efficiency of farming on them. Forecast of radionuclides and heavy metals behavior in the soil-plant system under the climate changes is developed in the laboratory. Ways to increase the resistance of plants to the stressors based on their exposure to the electromagnetic fields with mm-wavelength are investigated.

Scientists of the laboratory explore the processes of spatial redistribution and transformation of physical and chemical forms of man-made radionuclides in soils and waters in the exclusion zone of Chernobyl NPP. New methods for assessing exposure doses of ionizing radiation on plants and animals inhabit natural ecosystems in the Polesye State Radiation Ecological Reserve are developed in the laboratory, and software for processing radiation measurement data and solving radiation safety problems are created here.

The Laboratory of Radioecology has all the necessary facilities for investigation in the field of radioecology: from sampling to radiochemical analysis and spectrometry measurements. The premises of the laboratory meet modern requirements of radiation safety standards.
