Abstract

A model which investigate long-term safety of a proposed surface disposal facility for low-level radium bearing radioactive waste was discussed. The models used for the investigation were a source term model, a groundwater flow and transport model, and biosphere model. The investigation focused on the migration of ²²⁶Ra, ²²²Rn, and ²¹⁰Pb to groundwater owing to infiltration of rainwater and the diffusive radon transport through the gas phase to the atmosphere. Results show that the dose contribution through the groundwater pathway is important than that through the atmospheric pathway.
