[en] Radiation doses to individuals in the future, living in the vicinity of a repository for HLW or spent fuel in crystalline rock, have been estimated. The same has been done for the collective doses. Within the Swedish Nuclear Fuel Safety project (KBS), the subsequent reviews and more recent work, a substantial number of scenarios have been treated in order to calculate the consequences of the release of radionuclides to the environment. The paper gives a quantitative discussion of the way in which different factors will influence radiation doses. The factors considered include canister degradation time, leach rate, groundwater transport time, geochemical retention, dilution effects and exposure pathways in the biosphere. (author)
