Outside of the battle between iPhone fans and Android advocates, few debates in the cell phone world are more divisive than that over whether the radio frequency (RF) energy emitted by cell phones is harmful. Though the industry and some members of the scientific community insist that there is no danger, other researchers and a growing number of public officials believe that there is cause for concern. No consensus exists, and as CNET has reported, any agreement or firm evidence may not come for a long time, if it does at all.
In the meantime, some CNET readers will feel more comfortable erring on the side of caution. If you're concerned, you can use a headset, text instead of talk, and limit calls when your carrier signal is low (more RF energy is emitted when a phone is working harder to reach a tower). Yet, since that advice isn't always practical, Pong Research has another solution, with a case that is designed to refocus RF energy, or radiation, away from your head while not reducing signal strength. So in other words, you can use your phone just as you normally would.
If you think that sounds like pseudoscience, I don't blame you. Honestly, I've never taken seriously the cheap radiation "shields" that you can find online. Usually nothing more than tiny stickers, I didn't believe that they did anything, except spread a false peace of mind. Few of the products backed up their claims with solid proof, and, even worse, some can actually interfere with your cell phone's signal. That's why I was pretty skeptical when I first heard of the Pong case. But as it turns out, the company has done its homework. … Read more
