[Stabiltiy and barries function provided by sanitary protective zone of radioactive waste neutralization site, according to data obtained through geoinformative technologies].

The authors defined a radioactive waste neutralization and disposal site as a complex of industrial chambers with used territory of ground with burial places, buffer sanitary protection zone and observation zone. This area is a complicated geotechnical zone where natural communities develop under chronic exposure to natural and artificial radionuclides coming from both global and technogenic sources. Using geoinformative technologies of radioecologic safety, the authors evaluated protective functions of buffer zone, its biopotential and stability to specific type of nature management. The studies helped to identify sorption and migration capacity of the territory.
