Investigation on medical radiation protection of medical and health institutions in Tibet Autonomous Region, 2020 / 中国职业医学

ABSTRACT

@#Abstract Objective （ ） To investigate the current status of medical radiation protection in medical and health institutions MHI Methods - （ ） in Tibet Autonomous Region. Sixty one MHIs in seven prefectures cities of Tibet Autonomous Region were selected as the study subjects by stratified random sampling. The radiological protection equipment and personal protective ， equipment were investigated and the quality control of radiological equipment and radiation protection monitoring in Results ， radiological workplace were monitored. There were 368 radiation workers in 61 MHI institutions accounting for 4.8% （ ） ∶ ， 368/7 701 of the total number of radiation workers. The ratio of male to female was 2 1 and the average was six people/ institution. The quantity of radiation monitoring equipment and personal protective equipment at all levels of MHI was less than ， 1.00 sets/person. Among them tertiary MHI had the lowest number of personal protective equipment configurations. The （ monitoring qualified rates of radiation equipment quality control and radiation protection in radiation workplace were 73.3% 88/ ） （ ）， 120 and 95.8% 115/120 respectively. The lowes tmonitoring qualified rate of radiation equipment quality control was 55.2% （ ） ， （ ， ）Conclusion 32/58 with digital radiography and the second was computed tomography 84.8% 28/33 . The monitoring ， qualified rate of radiation protection in MHI workplaces at all levels in Tibet Autonomous Region is high. However radiation monitoring equipment and personal protective equipment should be increased.
