Abstract:Objective To find out about radiation protection inside radiodiagonsis facilities at 19 hospitals in one area over the past 10 years in order to provide guidance for radiation protection and to control radiation hazards efficiently.Methods According to the national related technical criterions and protection standards, the radiodiagnosis facilities at 19 hospitals in one area were selected as targets of research., Key indexes about radiation protection were statistically analyzed.Results The number of radiodiagnosis facilities was 104 in 2005 and 107 in 2015. Although the number has hardly changed, the radiodiagnosis equipment has been updated over the past ten years. The unqualified percentage of radiation protection indexes has dropped obviously. The unqualified rate associated with radiation leakage from the control station, doors for doctors and doors for patients dropped from 12.5%,18.3% and 21.2% in 2005 to 0%,0.935% and 0.935% in 2015. The 12 work places The ambient dose equivalent rate was above 2.5μSv/h inside twelve facilities in 2005, but wasless than 2.5μSv/h in 2015. The key protection indexes dropped from 57.5%,44.2% and 76.9% to 20.6%,1.87% and 1.87% in 2015.Conclusion The effect of radiation protection has been getting better in 19 hospitals over the past ten years, but the awareness and scope of radiation protection need to be improved.
