The UK Health Protection Agency (HPA) has been monitoring the safety of Wi-Fi. It says peopleusing Wi-Fi, or those in the proximity, are exposed to the radio signals it emits - and some ofthe transmitted energy in the signals is absorbed in their bodies。
英国健康保护署曾检测Wifi的安全性。它的调查结果称,使用或者接近Wifi的人群都在其辐射范围内,而且信号中传送的一些能量会被吸取进身体中。
However, the signals are very low power. Sitting in a Wi-Fi hotspot for a year results in receivingthe same dose of radio waves as making a 20 minute mobile phone call。
然而,这些信号的能量很低。在Wifi热点附近坐上一年所吸取的辐射,大约等于20分钟通话所产生的无线电波。
