| The mobile communication base station transmitting electromagnetic radiation on the surrounding environment, and has certain influence to the human body.Field testing of mobile communication base station electromagnetic influence, predict safety range and distance is one of the important measures to safeguard the personal safety.This paper select XiMeng unicom branch has built 163 45 typical base station in the mobile communication base station environmental impact monitoring and analysis, and forecasts the safety margin, and the following conclusions.1. The base station environment functional characteristics, the selection of typical 45 stations can reflect the current state of the study area 163 base stations to monitor the environmental features.2. The present situation of professional exposure monitoring study, status monitoring of five operating room internal communication base station, the cabinet and feeder outlet of measuring value in mμW/cm2 interval (0.1～1.2), both in the occupational exposure limit (200μW/cm2) range, meet the requirements of occupational protection of electromagnetic radiation.3. The status quo of public exposure monitoring research of XiMeng running 45 typical stations in 43 measured value is lower than 3.9μW/cm2, the han 2 (maximum 731 radio) base test value of 6.2μW/cm2, but lower than the standard limit 8 mμW/cm2.People’s procuratorate of the base peak of 9.7 mu W/cm2, beyond a single project to the public caused by the electromagnetic radiation dose limits.4. Through GSM900, GSM 1800, WCDMA and colocation base station electromagnetic radiation prediction results show that the theoretical calculation of typical stations GSM900 typical GSM 1800 typical stations of base station, China unicom, China unicom WCDMA base station, typical unicom GSM900+GSM 1800 typical base, unicom GSM900+WCDM typical typical and GSM1800+WCDMA base station, unicom unicom GSM900+GSM1800+WCDMA base station typical prediction of electromagnetic radiation on the main lobe antenna axis, the distance is greater than 24 m,24 m respectively,17 meters,34 meters,30 meters,30 meters and 38 meters conform to the environmental impact assessment standard limit (8 mu W/cm);Forecasting point not on the antenna axis, the distance is greater than the 17 meters,17 meters,12 meters,24 meters,21 meters,21 meters and 27 times conform to the environmental impact assessment standard limit (8μW/cm2). |
