摘要

In this study, the radiation dose to an occupant living in a dwelling constructed with uranium mine waste rock was estimated. The RESRAD-BUILD software was used to simulate radiological exposure in a model room, where both the floor and ceiling were made using different compositions of uranium mine waste rock. The model room had standard dimensions of 5 × 4 × 2.8 m, with the floor and ceiling built from concrete incorporating waste rock as coarse aggregate (gravel). The occupant was assumed to be located at the center of the room, 1 m above the floor. Potential exposure pathways included external exposure and inhalation of radon and its progeny. The additional dose to the occupant was found to be 0.95 mSvy−1 for a waste rock composition of 30%, which is below the public dose limit of 1 mSvy−1. Additionally, radon concentrations within the room, attributable to the waste rock, ranged from 8.8 to 33.8 Bqm−3 for waste rock compositions of 25–100%, significantly lower than the recommended action level for radon.
