As an electronic engineer I witnessed the testing of several devices which claimed to reduce cellphone radiation into the brain. Most of these devices used an adhesive backing to stick them to the phone. The test used a dummy head which contained a plurality of highly sophisticated radiation sensors. The cellphones being tested were placed over the ear.

As I suspected, the devices were 100% useless. The radiation picked up by the sensors was essentially the same with or without the devices being attached to the cellphones. Many different brands of cellphones were tested with the same devices. The results were the same. I found it very sad that some of these devices were recommended by famous doctors. These good people may be great doctors but they are not radio frequency engineers. I personally believe that cellphones are incredibly dangerous. My advice is to do as Dr. Mercola suggests and buy a non Bluetooth headset. It is also a good idea to use a speaker phone adaptor for your car and be sure to keep cellphones away from children.

after having a cell phone for a few years and now not having one any longer, i don't miss it at all. Last year I acquired one and used it for a good six-seven months and I didn't gain anything except my work bothering me all the time and I lost about $60 a month. It would just disappear. Now that I don't have a cell phone, there are very few instances where I am annoyed and can't deal without one.

I work at a job that has NO landline but everyone but me has a cell phone, so if I need to make a call, I just ask one of the guys to use theirs. When I am off work, I am usually at home, around the phone, or with someone who has a cell phone. You should try this practice and you will find that you will gain $60 more a month and lose 10 pounds of weight and your teeth will be whiter.

Cell phone radiation (photons) are carcinogenic, though  not as high-energy as x-rays, a Class A carcinogen.  Keep warning about it.  Take a look at a major photon-damaging practice: mammograms.  Doctors ignore and in fact cause cancers: X-rays are photons with 100 to 1000 times more energy than untra-violet, for which they prescribe sun-block.   C-ray damage is cululative.  Only one x-ray photon can ionize one electron in one human cell, and that electron can damage one DNA.  If it hits chromosome 17, which controls reproduction, you get cancer.  Now consider that a typical mammogram shoots about three million photons through a breast.  One cc of human tissue -- about a half-inch cube -- has 675 million cells for targets.  Each cell gets about 1.33 photons through it.  Dr. John Gofman's book proves diagnostic x-rays are the major cause of cancers.  Since mammograms have been urged on all worried women, the fatalities from breast cancer have gone UP 328 percent, not down.  Doctors refuse to learn or be concerned, and don't even ask patients how many x-rays they have already had.  Please check this out and alert women.
