人体与手机不同距离下比吸收率的研究

Research of Specific Absorption Rate under the Condition of Different Distances between Human Body and Cell Phone

参照EN 62209-1、OET 65C的测量方法及相关要求,基于瑞士SPEAG公司生产的DASY 5测试系统,对6个品牌的手机进行了比吸收率测试。研究了手机分别工作在GSM和WCDMA两种模式下,与人体不同距离时人体对其电磁辐射比吸收率的变化。结果表明,OET 65C测试的SAR值要比EN 62209-1测试的SAR值大,且手机对身体部位的辐射更应引起重视。

According to the measurement methods and requirements of EN 62209-1 and OET 65C, based on DASY 5 test system, the specific absorption rate （SAR） for six brands of cell phones were tested. The change of SAR value was researched when mobile phone worked in GSM and WCDMA modes respectively with different distances from the human body model. Test results showed that the SAR values tested by OET 65 C were bigger than EN 62209-1, and the radiation on body regions should be more concerned.
