本研究探討病房護理人員對醫用游離輻射及防護相關因素認知。採結構式問卷，自2009年9月起於中部某區域教學醫院病房護理人員，發放問卷共183份，以了解護理人員對輻射之認知。有效問卷共166份(n=166)回收率達90.7％。經分析後得知病房護理人員對於輻射防護及游離輻射執業安全知識，有相當程度認知，但對較深入的概念性及專業性題目正確率仍偏低；執業安全認知方面會因工作部門(p＜0.05)、畢業至今的工作年資(p＜0.05)、樣本醫院工作年資(p＜0.05)而有顯著性差異；輻射安全教育方面，護理人員有高度需求及高認知率。本研究結果提供醫療管理者進行職前或在職教育及預防職業危害之宣導和護理教育界作為課程設計之參考，建構護理人員正確的輻射及防護觀念，降低對醫用游離輻射的疑慮，保障護理人員臨床工作輻射暴露時的安全，增進醫療照護品質。

Object：The purpose of this study was to discuss the correlation factor cognition of the medical ionizing radiation and protection for the hospital ward nursing staffs.Materials and Methods ： The structural formula questionnaire was applied in this study.The questionnaire included one hundred and eighty-three copies to a regional teaching
hospital that located in the middle of Taiwan from September, 2009. This questionnaire was for understanding the cognition of radiation to the ward nursing staffs.Results：One hundred and sixty-six effective questionnaires(N=166)were collected from the hospital ward nursing staffs. The ratio of returning reaches 90.7%. The questionnaire results
via analysis showed that the hospital ward nursing staffs possess the cognition of the radiation shield and the ionizing radiation disciple security knowledge, but the rate of accuracy was somewhat low to the conceptive and the specialized questions. It would have the significance
differences in the disciple security cognition because of the work department (p<0.05),the work period of service since graduation(p<0.05), and the sample hospital work period of service (p<0.05) In point of the radiation safety education, the nursing staffs have great requirement
and high cognition.Conclusion：This study provides the reference resources for medical superintendent to proceed the projects of pre-service training and on-the-job training, the guidance of prevention
of occupational injuries, and the nursing educational. Besides, it helps the nursing staffs buildup the correct concept of radiation protection, reduces the anxiety about the medical ionizing radiation. Ensure the nursing staffs against being exposed radiation as working clinically
and develop the quality of medical nursing.
