[On quality grade of geologic barriers in construction and running the near-surface depots for radioactive waste with low and medium activity].

The article contains data on changed state of natural (geologic) barrier in construction and running the depots for radioactive waste. The authors stress over 10-fold increased water-permeability of upper part of radioactive waste placement ground, formation of antropogenous (technogenic) water-bearing level and changed filtration flow direction. Based on radionuclides migration modelling, the authors determined possibility of more intensive relocation of radionuclides in subsoil.
