Know your handphone radiation levels

Here is something that is of very important information in regards to handphone radiation level.

According to the Cellular Telecommunications Industry Association, specific absorption rate, or SAR, is "a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body." For a phone to pass FCC certification and be sold in the United States, its maximum SAR level must be less than 1.6 watts per kilogram. In Europe, the level is capped at 2 watts per kilogram while Canada allows a maximum of 1.6 watts per kilogram. The SAR level listed in our charts represents the highest SAR level measured with the phone next to the ear as tested by the FCC. Keep in mind that it is possible for the SAR level to vary between different transmission bands (the same phone can use multiple bands during a call), and that different testing bodies can obtain different results. Also, it's possible for results to vary between different models of the same phone--such as a handset that's offered by multiple carriers. CNET lists the exposure for voice calls only; the SAR for data use can differ.


If you're concerned about limiting your SAR exposure, you can take a few easy steps beyond purchasing a handset with a low SAR. You can text instead placing a voice call, use a wired headset or speakerphone whenever possible, and carry your phone at least one inch from your body. Some researchers also caution against using your phone in areas with poor coverage since phones emit more radiation when searching for a signal. Children, which have smaller and thinner skulls, should limit cell phone use, and all users, children and adults, should not sleep with an active phone next to their bedside or under their pillow.
