- Minimize your contact with cellphone as much as possible: use land line phone or text messages.
- Children should not be allowed to expose to cellphone, or at least for an extended period.
- If you have to, reduce your contact with cell phone when it establishes contact with the cell tower – low battery or on the move.
E.g.: put the phone far away from your ear when you are dialing, and bring it closer to you when you are listening
use earphone, or put your phone on speaker mode when possible
