Effect of Cell Phone radiation and Precautions To Reduce it

What is Cell(Mobile)Phone Radiation?

Whenever your cell phone is turned on, it is emitting potentially harmful EMF(ELECTRO MAGNETIC FIELD) radiation. Possible side effects can range from disrupted sleep patterns to changes in DNA. When you hold your cell phone up to your ear, 10% to 80% of the radiation from the phone penetrates two inches into your brain. In children, the penetration is even deeper. Studies have shown that cell phones held near the head cause brain wave changes in 70% of people. 
The effect of mobile phone radiation on human health is a subject of interest and study worldwide, as a result of the enormous increase in mobile phone usage throughout the world.
What are the dangers of mobile phones?
Despite extensive research on the subject, there has been no conclusive evidence that using a mobile phone causes long term harmful effects in humans.
The pace of mobile phone technology is advancing at a far quicker pace than the research required into the potential harm they can cause; much more research is needed (and is being undertaken) before we can know for certain the effects they have on human health.
Studies have shown that exposure to the RF(Radio Frequency) waves emitted from mobiles can cause:
  • Headaches
  • Genetic damage
  • Impaired immune system
  • Cancers, including brain tumors and melanoma
  • Break in the brain/blood barrier
  • Reduced melatonin
  • Interference with pacemakers
  • Memory loss
  • Changes in electrical activity in the brain
  • Cardiovascular stress
  • Fatigue
  • Eye problems
The health risk is considered to be very, very small, although some individuals may be more susceptible to radiation than others.
Whilst it's true that excessive exposure to RF waves causes heat to be generated, the spoof claims you may have heard about being able to cook an egg using a mobile phone are entirely false.
Nevertheless, mobiles do emit low doses of radiation so common sense dictates that precaution should be taken when using them.
Here are some important tips to minimize exposure:
1. Keep some distance – 
Hold your cell phone as far away from your body as possible. Moving your phone 20cm away from your head reduces radiation doses by about 98%. So instead of placing it under your pillow when going to bed, leave the phone at a bedside table.

2. Use a Wired or Bluetooth Headset

Use a headset (wired or Bluetooth) to keep the handset away from your head.

3. Do Not Press Handset Against Your Head

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 your Calls

Limit the length of mobile calls as you will be exposed to radiations for lesser amount of time if you don't go on talking for long. Try not to chat for hours on end or, if you must, get a hands free kit

5. Use text (SMS) instead of voice wherever possible.

This pings the cell phone towers for seconds rather than minutes and minimizes your radiation exposure. This would allow you to keep the instrument away from your head and you will be saved from unnecessary radiations.

6. Put the cell phone on speaker mode

Use the speakerphone on your cell phone when you can have a public conversation, or hook your cell phone up to an earphone or headphones to keep it as far from you as possible while still talking on it.

7. Use Phone Only When You Have Good Signal Strength

Use your phone where reception is good. If the radio signal is weak, amobile phone will increase its transmission power. Find a strong signal and avoid movement.

8. Avoid Mobile Phone with Metal Framed Glasses

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. Wait for the Call to Connect before you Put it on Ear

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. Use a Wired Landline Phone

When you are home, use a wired landline. Remember, cordless phones connected to a landline can emit radiation much like cell phones.

11. Avoid Keeping the Switched On Phone in Upper Pocket

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 Usage

Reduce children's mobile phone use, as a younger person will likely have a longer lifetime exposure to radiation from cell phones.

13. Keep your Cellphone Away if you Have Medical Implants

People who have active medical implants should preferably keep the cell phone at least 15cm away from the medical implant.

While purchasing a mobile handset, check its SAR value. This can be found on the internet if you know its make and model.

SAR stands for Specific Absorption Rate, this value signifies the amount of radiation (in Watts) which is absorbed by per unit KG of your body. The maximum value limit allowed in India is 1.6 W/Kg, this calculation for SAR value is usually done by the manufacturers of the smartphones and then sold out in the market. Any smartphone having a SAR value more than this number cannot be sold in India.

14. Reduce Use of Mobile Phones when in a Car

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.

15. Place your Cell Phone on Both Ears Interchangeably

Switch sides regularly while communicating on your cell phone to spread out your exposure. Earlier, reports have surfaced stating that the radiations are less harmful when phone is placed on the left ear, but seems that wasn't correct.

16. Avoid Talking in Enclosed Metals Spaces like Airplanes

Try not to use your cell phone in elevators, trains or planes. Cell phones draw more power, and emit more radiation, in enclosed metal spaces.

17. Consider Radiation Protection Devices

Lastly, consider investing in some form of radiation protection. There are tons of products out there, such as Global Healing Center’s cell phone radiation protector. You can also protect yourself from radiation in your home by placing a large electromagnetic field protector in the area.


  1. Great tips. Most telecome companies deny harmful effects of mobile radiations because of their vested interest, but reality is something else. Thanks for sharing
