Precautionary guidelines issued by DoT on mobile phone radiation
Precautionary guidelines issued by DoT for mobile users:
- Keep distance – Hold the cell phone away from the body to the extent possible.
- Use a headset (wired or Bluetooth) to keep the handset away from your head.
- Do not press the phone handset against your head. Radio Frequency (RF) energy is inversely proportional to the square of the distance from the source-being very close increases energy absorption much more.
- Limit the length of mobile calls.
- Use text as compared to voice wherever possible.
- Put the cell phone on speaker mode.
- If the radio signal is weak, a mobile phone will increase its transmission power. Find a strong signal and avoid movement – Use your phone where reception is good.
- Metal & water are good conductors of radio waves so avoid using a mobile phone while wearing metal-framed glasses or having wet hair.
- Let the call connect before putting the handset on your ear or 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 the call connecting time.
- If you have a choice, use a landline (wired) phone, not a mobile phone.
- When your phone is ON, don’t carry it in the chest / breast or pants pocket. When a mobile phone is ON, it automatically transmits at high power every one or two minutes to check (poll) the network.
- Reduce mobile phone use by children as a younger person will likely have a longer lifetime exposure to radiation from cell phones.
- People having active medical implants should preferably keep the cell phone at least 15 cm away from the implant.
