Abstract: According to the relevant national standards and methods of radiation health, in order to protect the health of radiation workers and the public, occupational hazard factors were identified in the workplace of a pressurized water reactor nuclear fuel element production line. And the gamma dose rate at sites, the average level of alpha and beta surface contamination on main process production posts, the concentration of alpha aerosol were monitored. The exposure dose and occupational health examinations of the workers were investigated as well. The results show that it is a project with serious occupational hazards. In normal operation, however, the radioactivity level of the workplace is in line with the requirements of Basic Standards for Ionizing Radiation Protection and Radiation Source Safety. It will not cause radiation damage to workers’ body.

Key words: PWR nuclear fuel element production, Radiation protection, Radiation impacts
