摘要
根据电磁场基本原理导出了计算影响量级及安全距离的通用公式,并依据相关标准,分析和计算了手机、手机基站的电磁辐射及防护安全距离。结果表明:使用手机在6 min内,GSM手机0.04 m、CDMA手机0.024 m以外,辐射的功率密度符合国家规定要求;对于手机基站,在距天线18 m以外,辐射强度对人体不会产生影响。
The common formulas for calculating the degree of the influence and the safe distance were derived based on the electromag- netism theory. According to the current national standards, the electromagnetic radiations and the safety distances of mobile phone and mobile communication base station were calculated. The simulation results showed that the radiation power density for GSM phone farther than 0.04 m from human body and CDMA phone farther than 0.024 m from human body could meet the demands of national standards using within 6 minutes. For the base station, the radiation intensity could not have the effect on the operator when the distance is farther than 18 m from the antenna.
