【摘要】：為研究大學(xué)生的手機(jī)電磁輻射暴露程度,針對手機(jī)的3種使用狀態(tài)(通話、發(fā)短信、上網(wǎng)),用TES-593電磁波污染強(qiáng)度計系統(tǒng)地監(jiān)測了36部手機(jī),監(jiān)測點(diǎn)代表耳朵、眼睛和手所在處。結(jié)果表明,所有監(jiān)測值均符合國際非電離輻射防護(hù)委員會(ICNIRP)的參考水平。3種使用狀態(tài)下的手機(jī)電磁輻射輻射強(qiáng)度大小依次為通話、發(fā)短信、上網(wǎng);在室內(nèi)通話、發(fā)短信和上網(wǎng)狀態(tài)下,2G手機(jī)近背面的平均電場強(qiáng)度依次為15.27 V/m、11.43 V/m和9.57 V/m;手機(jī)在室內(nèi)通話狀態(tài)下的電場強(qiáng)度大于室外通話狀態(tài)下的電場強(qiáng)度,2G手機(jī)在這兩種狀態(tài)下,聽筒處的平均電場強(qiáng)度分別為16.00 V/m、9.46 V/m。多數(shù)手機(jī)室內(nèi)通話電場強(qiáng)度容易超過GB 8702—88《電磁輻射防護(hù)規(guī)定》的參考值。手機(jī)發(fā)短信、上網(wǎng)時的輻射強(qiáng)度隨距離增大而減小,一般情況下不會超過《電磁輻射防護(hù)規(guī)定》的參考值。
[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.
