Contribution to a more realistic approach in assessing the release of C-14 from low-level radioactive waste repositories.
The contribution of C-14 to radiation exposure in the biosphere can be significant as compared to that of other radionuclides disposed in a repository for low-level radioactive waste. The release pathways of C-14 and processes relevant to its release from a closed final repository for low-level radioactive waste are discussed. Because a conservative approach may lead to undue overestimation of the potential radiation exposure, a more realistic approach is outlined. At the present level of refinement, our approach helps to provide a sufficient safety margin to German dose limits for radiation exposure of 0.3 mSv and can thus facilitate licence approval.
