According to the emission of pollutants during the operation of a reduction ilmenite (associated radioactive ore) project, the individual effective doses of different exposure routes on the surrounding public were predicted, and the contribution of different exposure routes were analyzed, to provide a reference for estimating the radiation dose of the project to the public. The results show that the maximum individual effective dose of the public members was 0.09 mSv/a, and the key exposure route was radon inhalation irradiation, which contributed 80.6%.The contribution share of ingestion exposure was 17.8%, the contribution of internal exposure due to radionuclides inhalation was 1.6%. The radiation impact of the project on the surrounding public meets the relevant standard requirements. Compared with radon inhalation exposure, the contribution of ingestion and inhalation exposure is smaller, but it cannot be ignored.
