Abstract
One of the greatest threat to human life is the radioactive contamination of the environment by manmade and natural radionuclides after accidents and disasters in nuclear industries. For example, after the accident at the Chernobyl Nuclear Power Plant (ChNPP) in 1986, the area of radioactive contaminated territories was 10 000 km2. In 1986-1988, in the exclusion zone of the ChNPP, temporary burial of radioactive contaminated materials was carried out without proper engineering site preparation of special repository.
Meanwhile, these land-buried wastes are sources of radioactive impurity of groundwater, which feed the river Pripyat and its tributaries, so there is a problem of their searches and reburials in specialized permanent repositories. This important task can only be solved with the help of detailed comprehensive geophysical researches.
The following main tasks are solved via the geophysical methods:
- contouring of trenches, excavations, dams, pits;
- searches and exploration of burial repositories, underground structures, burial sites of radioactive contaminated materials.
The specifics of identification of burial sites of radioactive contaminated materials is to determine the radiometric parameters of radioactive contaminated materials and their enclosing soils and rocks.
