Abstract Objective To investigate the radiation awareness of occupational staff in a typical rare earth ore. Method A questionnaire for the radiation awareness was designed through field observation, literature query and consulting professionals. And the survey was conducted among the occupational staff via the random cluster sampling method. Results The overall level of radiation awareness among occupational staff was generally poor. The cognitive scores of ionizing radiation, internal and external exposure and their main types were higher in the lower dust group than those in the higher dust group (P<0.05), and the cognitive scores on radiation hazard in the lower dust group were also slightly higher than those of the higher dust group (0.05 < P < 0.1). However, there were no statistically significant of age, education level, the pathways of obtaining the radiation-related knowledge, and the knowledge of preventive measures for internal and external radiation between the two groups. Conclusion The overall radiation awareness of occupational staff in the typical rare earth ores should be enhanced, especially for the staff working in the high dust and aerosol concentration environment. The protection awareness was insufficient and radiation training should be strengthened.
