【摘要】：为研究大学生的手机电磁辐射暴露程度,针对手机的3种使用状态(通话、发短信、上网),用TES-593电磁波污染强度计系统地监测了36部手机,监测点代表耳朵、眼睛和手所在处。结果表明,所有监测值均符合国际非电离辐射防护委员会(ICNIRP)的参考水平。3种使用状态下的手机电磁辐射辐射强度大小依次为通话、发短信、上网;在室内通话、发短信和上网状态下,2G手机近背面的平均电场强度依次为15.27 V/m、11.43 V/m和9.57 V/m;手机在室内通话状态下的电场强度大于室外通话状态下的电场强度,2G手机在这两种状态下,听筒处的平均电场强度分别为16.00 V/m、9.46 V/m。多数手机室内通话电场强度容易超过GB 8702—88《电磁辐射防护规定》的参考值。手机发短信、上网时的辐射强度随距离增大而减小,一般情况下不会超过《电磁辐射防护规定》的参考值。
[Abstract]:In order to study the degree of electromagnetic radiation exposure of college students, 36 mobile phones were systematically monitored by TES-593 electromagnetic wave pollution intensity meter in view of three kinds of mobile phone usage states (telephone, short message, Internet). The monitoring points represented the ears, eyes and hands. The results showed that all the monitoring values were in accordance with the reference level of ICNIRP (International Commission on Non-ionizing radiation Protection) (ICNIRP). The average electric field intensity on the near back of the phone is 15.27 V / m 11.43 V / m and 9.57 V / m, respectively. The electric field intensity of the mobile phone in the indoor call state is higher than that in the outdoor phone state. The average electric field intensity at the receiver is 16.00 V / m ~ (-1) and 9.46 V / m ~ (-1) respectively. The electric field intensity of most cell phone calls easily exceeds the reference value of GB 8702-88 electromagnetic radiation Protection regulations. The radiation intensity decreases with the increase of distance and does not exceed the reference value of electromagnetic radiation Protection Regulation.
