Reducing the effect of mobile radiations on human life is a major concern.

Conference Paper Low cost solution for reducing the effect of mobile radiations

Simple precautions to reduce the levels of radiation you absorb from using your phone include:

• 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.
• Hands free headsets dramatically reduce radiation emissions into the brain
• Try not to chat for hours on end or, if you must, get a hands free kit
• There are a few devices on the market that you can fit to your phone that reduce the emissions of radiation or allow the body to neutralise the effects, but beware of over-hyped promotions by these manufacturers using scare tactics to market their products.
• It's always sensible to take precautions where children are concerned as their developing brains and bodies are far more susceptible to radiation effects than adults, absorbing radiation at three times an adult's rate.

very good topic

There is no strong or consistent evidence that mobile phone use increases the risk of getting brain cancer or other head tumors. The United States National Cancer Institute points out that "Radiofrequency energy, unlike ionizing radiation, does not cause DNA damage that can lead to cancer. Why is there concern that cell phones may cause cancer or other health problems? ... Cell phones emit radiofrequency radiation (radio waves), a form of non-ionizing radiation, from their antennas. Parts of the body nearest to the antenna can absorb this energy.

Keep your distance. Do not keep your cell phone next to your body or in your bra. ...

Talk on speaker. Holding a cell phone to your ear also exposes your salivary glands to EMFs. ...

Turn your phone off more often. No radiation is emitted when the device is off.

Consider alternatives. ...

Use an EMF shielding device. Try to keep the cell phone away from your head and body. ...

When talking on the cell phone, use speakerphone or wired airtube headset to reduce exposure to your head.

Avoid carrying your phone against the body like in a pocket, sock, bra or spandex pants.

Use Time Distance and Shielding to Protect Yourself. Putting distance and shielding between you and a radiation source is an immediately effective way of reducing your exposure. Reducing the time you are being exposed is another way. Use a Respirator or Face Mask if You are exposed to airborne sources.
