手持式移动电话微波辐射强度的调查分析

Studies on the microwave leakage in the handportable mobiletelephone

为探究手持式移动电话（ＨＭ）微波漏能情况与使用电磁波防护套的效果，作者对２个牌子２种型号１０部ＨＭ进行了微波辐射强度的调查分析。结果显示，在正常通话时，２种型号ＨＭ微波辐射的功率密度平均分别为６２３ｍＷ／ｍ２（天线部范围８６０～３５００ｍＷ／ｍ２）和５３１ｍＷ／ｍ２（天线部范围８４０～２５００ｍＷ／ｍ２），均超过国家微波卫生标准。ＨＭ不同部位微波漏能主要为天线部和听筒部。戴上电磁波防护套后，２种型号ＨＭ微波辐射功率密度明显降低，其防护效率７９１０％～８２３４％。讨论了ＨＭ微波漏能的特点及其对人体的潜在影响。

The microwave leakage in the handportable mobiletelephone (HM) and the effect of electric magnetic wave protector were studied The results showed that the intensity of microwave leakage in the HM of two models were averagely 623 mW/m 2 (aerial part ,ranging 860～3500 mW/m 2)and 531 mW/m 2(aerial part,ranging 840～2500 mW/m 2)respectively,all exceeding the standard of microwave in China,during the normal communication by the HM The microwave leakage from HM were mainly the aerial part and receiver part By taking the electric magnetic wave protector of HM,the intensity of microwave leakage of those two models were all significantly lower The protective effectiveness rate to microwave were from 79 10% to 82 34% The characteristic of microwave leakage in the HM and the fluence of the potential for microwave in human were discussed
