History:

The laboratory 04 «Rehabilitation of contaminated areas» was founded in April 2000. The purpose of creation is to conduct research of physical-chemical and sorption properties for radionuclides 137Cs and 90Sr of soils, natural organic and mineral raw materials, industrial wastes and sorbents based on them for the development of methods for the rehabilitation of radioactively contaminated soils in Belarus as a result of the Chernobyl accident.
On October 16, 2017, laboratory 04 “Rehabilitation of technologically contaminated territories” was merged with laboratory 02 “Nuclear Physics and Environmental Technologies” to ensure the effective functioning of laboratory 04 “Rehabilitation of contaminated areas”.

The main directions of scientific research (fundamental and applied), projects:

1) Study of the physicochemical properties, selective sorption capacity of soils, organic and mineral substances and industrial wastes, as well as sorbents based on them for radionuclides 137Cs and 90Sr;
2) Development of various products based on natural mineral raw materials (treble, bentonite clay, sand) and industrial wastes (clay-salt slurries), including sorbents for the purification of NPP’s liquid radioactive waste of low and medium activity and matrices for the immobilization of radioactive waste, barrier materials for the safe storage and disposal of radioactive waste from NPP.
3) Development of methods for the rehabilitation of soils contaminated as a result of man-made accidents, using sorbents based on natural organic and mineral raw materials and industrial wastes, mathematical models for predicting the behavior of radionuclides 137Cs and 90Sr in environmental objects (soil, aquatic ecosystems).
4) Development of methods and technological solutions for the economically justified use of natural organic and mineral raw materials and industrial waste in various spheres.
5) Study of changes in physical-chemical properties of organic substances under the action of various sources of ionizing radiation using radiation technologies.
6) Development of scientific foundations for new technologies for protecting the environment and humans from oncogenic pollutants.
