中文摘要：
目的调查上海市某区放射工作人员对辐射基础、防护、应急等知识的知晓和需求情况。方法对上海市某区150名放射工作人员发放问卷式调查表，对回收的147份问卷结果进行统计学处理。结果所调查放射工作人员知晓率最低的是辐射有关基础知识方面的问题（84．76％），对放射知识需求率最高（95．24％）。不同学历、不同年龄、不同行业放射工作人员之间辐射有关基础知识、辐射防护知识认知情况差异有统计学意义（P〈0．05）。放射性对人体危害情况知晓率仅在不同学历放射工作人员间差异有统计学意义（P〈0．01）。辐射应急知识、放射法律法规的知晓率、放射知识需求情况调查在学历、年龄及职业方面差异无统计学意义（P〉0．05）。结论上海市某区放射卫生工作人员具备一定的辐射知识。应继续加强放射卫生基础和辐射防护知识方面的宣传和培训力度，提高该区重点人群放射工作人员辐射知识的认知水平。
