How Our Bodies Absorb Cell Phone Radiation
Different cell-phone models emit different amounts of radiation, so one way to reduce your exposure is to purchase a cell phone with a lower SAR (specific absorption rate), a number that indicates how much radiation is absorbed by the human body when the handset is being used at maximum power. The Environmental Working Group has compiled a list of SAR values for most cell phones.
SAR values are useful, but they are bound to increase as cell phones become more powerful and add new features and applications. How you use your cell phone is a much better way to control your exposure to cell-phone radiation.
Lower Your Exposure to Cell Phone Radiation
Keep Your Distance
Find a Strong Signal and Stay Put--When your cell phone has a weak signal, it has to work harder to transmit and receive, and that equals higher bursts of radiation.Your cell phone is forced to repeatedly emit new bursts of radiation as it connects to different cell towers along your route.
Wait to Speak and Listen--Most cell phones emit the most radiation when they first connect with the cell tower. One way to reduce your exposure to cell-phone radiation is to wait until your call has been connected before you put the phone to your ear.
Use the Toggle Method--Because cell phones emit significantly more radiation when they are transmitting signals than when they are receiving, you can reduce your radiation exposure by holding the phone away from your ear when you are talking and only bringing it close to listen.

Lower Your Exposure to Cell Phone Radiation
Keep Your Distance
- Using a wired headset
- Putting your cell phone on speaker mode
- Using a wireless Bluetooth headset or earpiece, which emit radiation at far lower levels than cell phones
- Carry your cell phone away from your body—in a purse, briefcase or computer bag—not in your pocket where it is pressed up against you.
