Yet they recommend the following:
To limit your exposure to #cellphone #electromagnetic emissions, the #FTC suggests that you:
- Increase the distance between your phone and your head by using a hands-free device, like an earpiece that is wired to the phone, or using the speakerphone feature.
- Consider texting more and limiting your cell phone use to short conversations.
- Wait for a good signal. When you have a weak signal, your phone works harder, emitting more radiation. Phones also give off more radiation when transmitting than when receiving, so tilt the phone away from your head when you’re talking, and bring it back to your ear when you’re listening.
- A phone’s specific absorption rate (SAR) reveals the maximum amount of radiation the human body absorbs from the phone while it’s transmitting. #SAR testing ensures that the devices sold in the U.S. comply with the Federal Communications Commission (FCC) SAR exposure limit, but the single, worst-case value obtained from this SAR testing is not necessarily representative of the absorption during actual use, and therefore it is not recommended for comparisons among phones. In short, selecting a lower SAR phone will not reliably ensure lower radiation absorption during use.
