Open AccessA near surface repository for low and intermediate-level short-lived radioactive waste will be built on the Stabatiškės site in the vicinity of Ignalina NPP during decommissioning works. The reservoir can also be used for the waste stored in the temporary repositories of the Ignalina NPP. Engineering and nature protective barriers are used in the repository for radioactive waste, however, radionuclides can spread into the environment, extend in the biosphere and cause (define) the external power light exposure of the environment due to the natural and premature (prescheduled) degradation of the engineering barriers of the repository. The properties of the soil (acidity, quantity of organic substances, humidity) are being investigated for estimating the possible migration and dispersion of radionuclides. The activity of radionuclides in the soil is also estimated before building the repository. Natural and artificial radionuclides make the pollution of the soil, and therefore the accumulation and vertical migration of artificial (137Cs, 60Co) and natural (226Ra, 232Th, 40K) radionuclides are being researched in the soil on the Stabatiškės site.
