Allocation of radiation protection equipment and status of occupational health management for radiation workers in investigated hospitals nationwide in 2019 / 中华放射医学与防护杂志

ABSTRACT

Objective:To investigate the allocation of radiation protection equipment and status of radiological protection management for radiation workers in hospitals nationwide.Methods:A descriptive analysis was conducted of the data reported from the investigated hospitals based the data for 2019 available from the National Radiological Health Information Platform.Results:A total of 3 806 hospitals were investigated in 2019, including 609 tertiary hospitals, 1 421 secondary hospitals, 1 776 primary and ungraded hospitals. Large differences had been shown in the number of radiation workers in different grade hospitals. The average number of radiation workers were found to be, respectively, 99 in tertiary hospitals, 19 in secondary hospitals, 2 in primary and/or ungraded hospitals. Interventional radiology and nuclear medicine workers were equipped seperately with 0.40 and 0.43 pieces of lead apron, 0.27 and 0.31 lead caps, 0.38 and 0.45 lead rubber neck sleeves, 0.18 and 0.08 pairs of lead rubber gloves and 0.31 and 0.22 pairs of lead glasses. No personal alarming dosimeter was available in 15.25% hospitals where radiotherapy was performed, nor radiation surveillance meter in 27.90% such hospitals. In the hospitals considered, 88.13% workers were granted the Radiation Worker Cetificate and 83.69% received the on-the-job radiation protection training. The number of monitored workers accounted for 99.20%, of which 0.40% received the personal annual dose Hp(10)≥20 mSv. The occupational health surveillance files that had been completed reached 98.05% of the total and the on-the-job radiation workers who had passed the occupational health examination made up to 96.00%. It was advised that, of 76 627 radiation workers who received the 2019 health examination, 0.88% should get out of radiation work for the being time and 0.11% should not continue for this work. Conclusions:The considerably large proportion of radiation workers in China have received individual dose monitoring and occupational health examination. Radiological diagnosis and therapy departments should enlarge the allocation of radiation monitoring and personal protection equipment for radiaton workers in their hospitals.
