India has experienced a phenomenal growth in the number of mobile phone users. The increased use of mobile phones in India has raised public interest in possible health issues associated with exposure to electromagnetic energy. People are concerned about exposure from mobile handsets & base stations.
Radio signals are part of everyday life, emitted both by natural sources like the sun, the Earth and the ionosphere, and by artificial sources such as: mobile phone base stations, broadcast towers, radar facilities, remote controls, medical, electrical and electronic equipment. The radio frequency sources in India are the transmitting towers such as AM, FM radio towers, TV towers, Cell phone towers, etc. emit radio frequency/ microwave radiation continuously. The level of EMF from sources has risen exponentially, by soaring popularity of wireless technology such as cell phones, cordless phones, Wi-Fi (Wireless Internet) Wi-max and other wireless devices. The mobile phone and its base station communicate using a two way radio communication. This radio communication produces Electro-magnetic fields.
It is important to understand what radio waves are and what their use is in our daily life. This document covers a basic introduction to radio waves, various terminologies, Do’s & Don’ts related to mobile phone usage, clarification of various myths regarding use of Radio waves/safety standards and frequently asked questions relating to Mobile phones & Human health. The document “Mobile Communication Radio waves & Safety” shall help in facilitating the right inputs and creating an environment where everyone can use the radio waves safely.
Conclusion:
The Precautionary Measures that need to be taken to avoid these radiations include:
- Wi-Fi Routers /Boosters should be placed at a distance.
- Switch off the Data Pack on mobile and Wi-Fi when not in use.
- While sleeping keep all the cordless devices at a safe distance from you
- Communicate through SMS as an alternate to calling.
- Use Wired Headsets for long conversations.
- Mobile Phones having ‘SAR’ value less than 1.6W/kg should be bought.
- Avoid placing mobile phones directly over pacemakers
- Keep distance – Hold the cell phone away from body to the extent possible
- Use a headset (or ear bud) to keep the handset farther from your head.
- Use a wired headset
- 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 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 shirt or pant 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.
