Abstract:
Objective To analyze the status of radiation protection among non-medical radiation institutions in Henan Province. Methods A total of 673 non-medical radiation institutions in Henan Province were selected as the research subjects using the judgmental sampling method. Their basic information and occupational health management practice were investigated. A total of 131 research subjects were selected for monitoring of occupational exposure to ionizing radiation using the stratified random sampling method. Results Among the 132 institutions using baggage inspection devices, none of the associated radiation workers (1 642 individuals) had received radiation protection training, personal dose monitoring, or occupational medical examination. Besides, among the remaining 541 radiation institutions with 8 373 radiation workers, the rates of radiation protection training, personal dose monitoring, and occupational medical examination were 62.2%, 98.1%, and 80.6%, respectively. The equipping rates for radiation monitoring instruments was 76.7%, for personal dose alarm device was 63.4%, and for the personal protective equipment was approximately 63.2% among the 673 non-medical radiation institutions. And the rate of independent monitoring for occupational radioactive hazard factors in workplaces was 65.2%, the rate of commissioned monitoring was 69.8%, the rate of conducting evaluations on the current status of occupational radioactive hazard was 70.4%, and the declaration rate of occupational hazard factor was 66.7%. The ambient dose equivalent rates for X/γ rays, neutron ambient dose equivalent rates, and average surface contamination levels of α/β particles in 131 radiation institutions met the national requirements. However, in three of the five underground metal mines, radon concentration exceeded 1 000.0 Bq/m³ at some operating detection points, with the highest one reaching 4 223.0 Bq/m³. Conclusion There remains a gap between current radiation protection practice in non-medical radiation workplaces in Henan Province and the requirements of national regulations and standards. Radiation protection management and supervision should be strengthened.
