3G各制式手机谁更“绿”色

Which Type of 3G Cell Phone is “Greener”

关于手机辐射到底对人体是否有害,多年来专家们对此一直争论不休。但是越来越多的研究成果表明,手机辐射能够破坏人体细胞和带有人类遗传信息的DNA,超过一定的辐射量是对人体构成危害的。3G移动通信系统WCDMA、cdma2000、TD-SCDMA由于采用的不同技术,其各系统中的手机在使用过程中对人体的辐射量也会有比较大的区别,下文中通过链路预算,比较了3种制式手机在实际使用过程中谁更“绿”色。

It has been years that scholars argue over whether cell phone radiation is harmful to human body. Now more and more research indicates that the cell phone radiation can destroy human cells and the DNA carrying human genetic information. As a result, the intake of cell phone radiation over a certain level will lead to negative effects on human body. Seeing that 3G mobile communications systems, respectively WCDMA, cdma 2000 and TD-SCDMA, are adopting various technologies, the cell phone of each mode differentiates remarkably in the volume of generated radiation while being used. In this regard, the article uses link budget, through a quantitive approach, to compare the three types of cell phones and concludes which is ＂greener＂ in real use.
