- Use a wired headset or the speaker phone feature if you're going to be spending a lot of time on the cellphone. The wireless, hands-free Bluetooth devices emit the same frequency of EMFs as cellphones (but weaker), so remove them as soon as your call is finished.
- Don’t clip your cell phone to your body.
- The electromagnetic fields are the strongest when your cell phone is connecting. If you don't want to use the speakerphone, put it up to your ear after the connection has been made (use the speaker phone while it’s connecting).
- If you’re buying a new cell phone, compare the SAR numbers. They can vary widely among cell phones. The lower the SAR the better. Here’s a CNET link where you can compare SARs for various types of cell phones.
