I know what you’re thinking. No really I actually do. The brain tumor in my head has lead to increased brain function just like Phenomenon starring John Travolta. Your thinking that cell phones have got to be okay, ‘they’ wouldn’t sell Barbie branded cellphones to kids of they knew they were harmful to developing brains, its inhumane! But all ‘jokes’ aside there is a lot to be said for the information out there that suggests that just like smoking was, the dangers of cell phone use are a closely guarded industry secret. While information based on short term studies may suggest otherwise, common-sense dictates that holding a microwave radiation emitting device to your head for extended periods of time is not a good idea. There is also research to support this claim such as the studies conducted by Dr. Lennart Hardell, among others.
In 2007, Dr. Lennart Hardell, from Örebro University in Sweden, reviewed published epidemiological papers (2 cohort studies and 16 case-control studies) and found that:
Cell phone users had an increased risk of malignant gliomas.
Link between cell phone use and a higher rate of acoustic neuromas.
Tumors are more likely to occur on the side of the head that the cell handset is used.
One hour of cell phone use per day significantly increases tumor risk after ten years or more.
A publication titled “Public health implications of wireless technologies” cites that Lennart Hardell found age is a significant factor. The report repeated the finding that the use of cell phones before age 20 increased the risk of brain tumors by 5.2, compared to 1.4 for all ages. A review by Hardell et al. concluded that current mobile phones are not safe for long-term exposure.

What can be done to minimise harm?
As part of the report, the EWG also provided eight safety tips for cellphone users who are concerned about radiation. Here is a quick list of the tips. You can click through to the original list for more detail on each of the items.
1. Buy a low-radiation phone
2. Use a headset or speaker
3. Listen more, talk less
4. Hold phone away from your body
5. Choose texting over talking
6. Poor signal? Stay off the phone
7. Limit children’s phone use
8. Skip the “radiation shield”
The EWG also offers a one-page PDF that lists all eight of these tips along with a further explanation of each. IT professionals might consider distributing this PDF to employees who use company cellphones or posting it on the corporate intranet. Of course, you should consult senior management and your legal department before distributing something like this since it involves employee health.

In 2005 Professor Lawrie Challis and others said clipping a ferrite bead onto hands-free kits stops the radio waves travelling up the wire and into the head. Several nations have advised moderate use of mobile phones for children.

What phones emit the most radiation?This company sells “SARS Shields” for cell phones. It is debatable whether they are of any benefit since shielding is likely to cause the cellphone to have to work harder to maintain a signal therefore making it emit more SAR but they do provide a handy index of SAR levels for all common models of mobile phone.More: http://www.cellphonesafety.info/radiation-shields.htmlhttp://www.sarshield.com/english/radiationchart.htmSome notes to consider in relation to the chart:
According to the Cellular Telecommunications Industry Association (CTIA), SAR or specific absorption rate is “a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body.” The SAR level listed in our chart represents the maximum SAR level for the phone.- North American Standard. The SAR limit for mobile phones used by the public is1.6 watts/kilogram (W/kg) averaged over one gram of body tissue.- European Standard. The SAR limit for mobile phones used by the public is 2.0 watts/kilogram (W/kg) averaged over ten grams of body tissue.- In order to compare relative radiation of different mobile phones, you can only compare phones using the same measurement.- Many questions are sent to us asking why our results differ from CNET on some model phones. CNET only publishes the SAR rating of the phone in the head position, we publish the HIGHEST SAR rating of the phone regardless of the position. We believe this is the proper rating.
Apple Vs. Google.Apple iPhone 4 clocks in @ 1.17 SARS (1.6W/kg)Google Nexus One clocks in @ .867 SARS (1.6W/kg)Modern application There is a new smartphone application which “analyzes your phone’s dynamic SAR (Specific Absorption Rate) levels, network coverage, location, environmental conditions and phone usage at any given moment”
“During a call (Call Mode) tawkon prompts you to take the easiest precautionary measures to minimize radiation given your current location and phone usage.”
