Derivation of site-specific derived concentration guideline levels at Korea Research Reactor 1 and 2 sites using probabilistic analysis.

The purpose of this study is to apply a probabilistic method to derive the derived concentration guideline levels for decommissioning of Korea Research Reactor 1 and 2. A total of seven parameters were found to be the sensitive parameters of the target nuclides. The DCGLs of Co-60 and H-3 were 0.063 Bq/g and 85.470 Bq/g, respectively. The concentrations of the gamma ray-emitting nuclides in the actual reactor sites were 7.7-215 times lower than the derived DCGLs for gamma ray-emitting nuclides.
