医务人员对医用电离辐射相关知识的知晓情况调查

目的 探讨医务人员对医用电离辐射相关知识的知晓情况。方法 选取2016年6月-2017年6月在我院工作的150名医务人员进行医用电离辐射相关知识及认知水平的问卷调查，并选取同期的非医务人员100例，对比分析所有医务人员对医用电离辐射的知晓度、从业感想及医务人员与非医务人员对医用电离辐射知识的获取途径。结果 医务放射人员对电离辐射基础知识的知晓率为48.0%，对辐射危害知识的知晓率为67.9%，对防护知识的知晓率为23.8%（P<0.05）；放射人员对于医用电离辐射的获取途径主要为专业书籍，其次为临床实践、媒体报道、网络，非放射人员对于医用电离辐射的获取途径主要为媒体报道和网络（P<0.05）；所有医务人员中，与男医务人员相比，女医务人员不愿暴露于电离辐射下工作所占比例较高，且对比不同科室的医务人员，其中医学影像学科室的医务人员不愿暴露于电离辐射下工作所占比例较高（P<0.05）。结论 医务人员对于医用电离辐射相关知识的知晓程度并不是很高，对相关知识的了解较为缺乏，因此要采取相应措施，加强医学辐射安全文化教育的宣传和普及，促使医务人员树立对待医用电离辐射的正确态度。

Investigation of knowledge about medical ionizing radiation among medical staff

Objective To investigate the knowledge of medical radiation exposure among medical staff.Methods 150 medical personnel who worked in our hospital in June-2017 in June 2016 were selected to carry out a questionnaire survey on medical ionizing radiation related knowledge and cognitive level, and 100 nonmedical personnel were selected for the same period. The awareness of medical ionizing radiation, the perception of employment and medical personnel and nonmedicalpersonnel on medical electricity were compared and analyzed.Results The awareness rate of the basic knowledge of ionizing radiation of medical radiologists was 48%, the awareness rate of radiation hazard knowledge was 67.9%, the awareness rate of protective knowledge was 23.8% (P<0.05), and the ways of obtaining medical ionizing radiation are mainly professional books, followed by clinical practice, media coverage, network.As for non radiant people,the main ways to obtain medical ionizing radiation are media coverage and network (P<0.05). Among all medical personnel, the female medical personnel are not willing to be exposed to the higher proportion of the workers under ionizing radiation compared with the male medical personnel, and the medical personnel in the medical imaging department of different departments are reluctant to do so. Exposure to ionizing radiation accounted for a relatively high proportion of work (P<0.05).Conclusion The awareness of medical ionizing radiation related knowledge is not very high and lake of related knowledge. Therefore, the corresponding measures should be taken to strengthen the propaganda and popularization of medical radiation safety culture and education so as to promote the correct attitude of medical personnel to treatment of medical ionizing radiation.
