北京市宠物医院X射线机使用及防护情况调查

目的 了解北京地区宠物医院X射线诊断设备的使用情况及防护管理水平。方法 对北京市13个辖区中共计292家宠物医院进行了实地调查，填写调查记录表；并对其中35家医院的机房外辐射水平进行了现场检测。结果 X射线诊断设备使用率为49.66%；职业病危害申报率6.90%，场所年度监测率25.52%，参加辐射安全与防护培训率22.07%，个人剂量监测率22.76%，职业健康检查率16.55%，上述要求全部满足的宠物医院仅2.07%；35家接受辐射防护水平现场检测的医院中防护合格率为34.29%。结论 北京市宠物医院中X射线诊断设备的使用率相对较高，但辐射防护工作尚存在明显不足，应引起相关单位的重视，加强管理。

Investigation on the use and protection of X-ray machines of pet hospital in Beijing

Objective To evaluate the usage situations and protection levels of X-ray diagnostic equipment used in pet hospitals in Beijing.Methods A total of 292 pet hospitals in 13 municipal districts of Beijing have been investigated. The radiation levels of 35X-ray rooms in these pet hospitals have been measured.Results The investigation results have been indicated with the utilization rate of X-ray diagnostic equipment, the application rate of occupational hazards, the annual measurement rate of radiation levels, the training rate of radiation protection, the monitoring rate of personal dose, and the examination rate of occupational health being 49.66%, 6.90%,25.52%, 22.07%, 22.76% and 16.55% in these pet hospitals respectively. Only 2.7% meet all of requirements above in all the pet hospitals investigated. Only 34.29% meet the standard requirements for the radiation protection levels of X-ray diagnostic equipment used in 35 pet hospitals in Beijing that received field tests.Conclusion Attention should be paid by management department for the relatively high utilization rate and low protection levels of X-ray diagnostic equipment in pet hospitals in Beijing.
