摘要
为了解目前高校内大学生拥有个人电脑的情况,以及大学生对其所产生电磁辐射污染的了解程度和受其危害程度,在南开大学本部选取有代表性的学生宿舍楼进行问卷调查。结果显示,大学生中个人电脑的普及率为45 .7% ,以电磁辐射强度相对大的阴极射线管(Cathod Ray Tube,CRT)显示器电脑为主,占64 .9% ;拥有个人电脑的大学生,平均每日使用电脑的时间长;学生使用电脑后出现不良症状(眼疼、头晕等)的比例高,为77.4% ,女生对电磁辐射的敏感程度高于男生;随每日使用电脑时间的延长,出现不良症状的人数增加;大学生对电磁辐射的危害有所了解的人数比例为71.9% ,但知道防护措施的仅为2 9.6% ,使用防护屏的仅为5 .4%。综合调查结果认为,大学生电脑普及率高,使用时间长,且对电脑电磁辐射无应有的防护,大多数大学生在一定程度上已经受到了电磁辐射的影响。
The present paper introduces the authors' survey on the students' use of personal computers (PC) and their likely electromagnetic radiation effect on their health in Nankai University, Tianjin. The result of the survey reveal that 45.7% of the college students own PC, and 68.6% of computers are equipped with Cathode Ray Tube (CRT). The average daily PC usage duration of the male and female students who own PC were 5.1 hours and 3.6 hours respectively. 77.4% of the college students suffer from symptoms dizzy, eye irritation and back pain after repetitive computers work. Female students are experiencing stronger symptoms than males. The percentage of the sufferers report that the problem has resulted from their increasingly daily use of computers and longer use duration. 71.9% of the students are clear about the hazards of electromagnetic radiation themselves, however, only 29.6% of them have taken protective measures. And among them only 5.4% have adopted protective screens. Thus, it can be concluded that: with high popularization of PC computers, low popularization of electromagnetic radiation protection facilities, and long duration of daily computer use, more and more serious impact has been found with electromagnetic radiation to some extent. As a newly found problem, much more attention should be paid to considerably.
