Currently, we have conducted a safety research project to review the framework of simplified shielding dose evalucation for Gamma-ray by considering the latest knowledge including the ICRP 2007 recommendations. In this presenation, we report on reevaluation of simplified dose calculation for two-layer slab shielding refering to the past research and how to incorporate it into the point-kernel integration code.
