EWG's Guide to Safer Cell Phone Use: 5 Safety Tips for Cellphone Use
USE A HEADSET OR SPEAKER
Choose either wired or wireless. If you go wireless make sure to take your headset out of your ear when you’re not on a call. Use your phone in speaker mode.
WHEN IN USE, HOLD PHONE AWAY FROM YOUR BODY
Why? The amount of radiation absorbed by your head and body decreases dramatically with even a small distance. Don’t put the phone in your pocket or clip it to your belt, even when using your headset..
TEXT MORE, TALK LESS
Phones emit less radiation when sending text rather than voice communications.
CALL WHEN THE SIGNAL IS STRONG
Fewer signal bars mean the phone must try harder to broadcast its signal. Research shows that radiation exposure increases dramatically when cell phone signals are weak.
Don’t store your phone in your pocket (or under your pillow)
When a phone is on and not in use, it still sends out an intermittent signal to connect with nearby cell phone towers, which means radiation exposure is still happening.
