上海市宝山区居民电磁辐射认知情况调查

Investigation on Electromagnetic Radiation Cognition among Residents of Baoshan District of Shanghai City

目的调查上海市宝山区居民对电磁辐射的认知现状。方法对160户居民采用问卷的形式进行调查。结果 42.3%的居民能够正确选出电磁辐射定义;不同学历居民对电磁辐射、电磁辐射准确定义及是否有害健康等问题了解情况差异有统计学意义,知晓率有随学历升高呈递增的趋势。媒体和书籍是居民获知电磁辐射知识的主要途径。38.2%居民偶尔或经常因担心环境中电磁辐射对的危害而失眠。住宅周围有变电站、高压输电线经过的居民经常出现头痛、头昏、失眠、记忆力减退、疲乏无力的比例与无变电站、高压输电线经过的居民相比,具有显著差异。结论目前宝山区居民对电磁辐射认识不足,建议加强相关宣传教育工作。

[Objective]To investigate the knowledge level of residents on electromagnetic radiation in Baoshan District of Shanghai City.[Methods]Questionnaire survey was performed on 160 families.[Results]42.3% of the respondents can select correct definition of electromagnetic radiation.Significant differences can be observed in awareness rates between residents with different education levels on electromagnetic radiation and its correct definition,and questions such as whether electromagnetic radiation was harmful to health;besides,there was an increasing tendency of awareness rate as education level rising.Media and books are main means by which residents get to know about electromagnetic radiation.38.2% of respondents sometimes or often suffered from insomnia for worrying about hazards of environmental electromagnetic radiation.The percentage of residents suffering from frequent headaches,dizziness,insomnia,memory loss and fatigue who lived with substation or high voltage lines nearby was significantly different from that of those lived far from substation or high voltage lines.[Conclusion]The knowledge level on electromagnetic radiation among residents in Baoshan District is relatively low currently,suggesting that relative publicity and education should be enhanced.
