1. Keep some distance – hold your cell phone as far away from your body as possible.
2. Use a headset (wired or Bluetooth) to keep the handset away from your head.
3. Do not press the handset against your head. Radio Frequency (RF) energy is inversely proportional to the square of the distance from the source — being very close greatly increases energy absorption.
4. Limit the length of mobile calls.
5. Use text (SMS) instead of voice wherever possible.
6. Put the cell phone on speaker mode.
7. Use your phone where reception is good. If the radio signal is weak, a mobile phone will increase its transmission power. Find a strong signal and avoid movement.
8. Metal and water are good conductors of radio waves, so avoid using a mobile phone while wearing metal-framed glasses or having wet hair.
9. Let the call connect before putting the handset to your ear or before you start speaking and listening – a mobile phone first makes the communication at higher power and then reduces power to an adequate level. More power is radiated during call connecting time.
10. If you have the option, use a landline (wired) phone rather than a mobile phone.
11. When your phone is ON, don’t carry it in chest/breast or pants pockets. It might harm your fertility or your heart. When a mobile phone is ON, it automatically transmits at high power every one or two minutes to check (poll) the network.
12. Reduce children’s mobile phone use, as a younger person will likely have a longer lifetime exposure to radiation from cell phones.
13. People who have active medical implants should preferably keep the cell phone at least 15cm away from the medical implant.
14. The RF radiation is increased by mobile phones when used in a car to overcome the window shielding. So try to reduce such use or stop it altogether.
