New technique to help study cell phone risks

A new antenna will help researchers determine if cell phone radiation poses a health risk to humans.

The subject of whether or not the electromagnetic waves emitted by mobile phones pose a cancer risk has been the matter of great debate and controversy ever since mobiles first appeared on the market. Unlike x-rays, the signal from a mobile is very low level - too low, presumably, to penetrate and damage cells. This would seem to rule out a health concern, however if too much radiation is absorbed there could still be a risk.

To help find an answer to this, researchers have developed a new type of non-metallic antenna that will allow them to use an MRI scanner on someone using their phone without the difficulties posed by the metal antennae used inside conventional handsets. In time this should facilitate the development of a full 3D map of cell phone radiation so that we can see once and for all whether exposure on a daily basis is truly having a negative impact on our health.

"To get a definitive answer, researchers need to be able to measure exactly how much radiation the brain absorbs during normal cell phone use--and they might finally have a way of doing it."

I have a cell phone, but I never really use it. Is that weird? It's the latest and greatest, but I tend to find that I don't really want people bugging me, so its always on vibrate and takes me forever to respond to texts lol. I have one too but it mostly stays in the glove box of my truck for emergencies and such. I don't feel this urgency to talk or text all the time. I prefer personal conversation myself.

I used to hear stories of people who were scared to live beneath hi voltage power transmission lines for the same reasons. I don't think a cancer link was proven there either.

i don't think cellphone microwaves and radio-waves are enough to create a problem by themselves. i believe that the cause of the rise in cancer is down to the fact that we constantly are exposed to all sorts of stimulus and environments that as a species we never evolved to withstand. so understandably; yet unfortunately, as with any species we have to have time to develop to our surroundings which in the past have been perhaps predators and loss of food supplies, but are now our own doings such as the chemicals and radiation we expose ourselves to. however it becomes a problem as our self cre...

I doubt if any new info will come of this as it seems the industry has been dancing around this subject since as long as I can remember. It will be one on those that keep their head glued to a phone day in and out because if they decide to sue the phone industry, I'm sure they'll get nowhere with it because all the studies that I've read have been labelled inconclusive. When phones were analog, I remember the retailers pushing headsets and urging customers to keep the phone away from their heads due to the heat, now its purely for distraction...

Even if the study confirms that cell phone use does cause cancer, it won't stop people from using them.

i doubt that they could use extra shielding as the signals need to be able to get in and out of the phone. you could always just use your headphones to prevent them being centered around your brain but then again these signals are used for tons of different devices so we're constantly so it would be hard to avoid the effects if there are any.

The problem with "Studies" is that most of the time they are funded by the people that stand the most to gain from a favorable report, ie the ones that make the product. Or the ones that sell the service to use with the phones, ie the mobile phone companys.

Even if the study confirms that cell phone use does cause cancer, it won't stop people from using them. just like with cigarettes, the cigarette industry fought for ages to stop it coming out that cigarettes were bad for people (and even intimidated alot of scientists with physical threats)

What about I-Pads then? Because they are totally wireless I'm sure the same amounts of lethal radiation are emanating from then. What however distinguishes a mobile phone from a I-Pad is that I feel no need to place the latter on my ear. I feel this radiation isn't imaginary and can cause severe brain damage in sustained doses. Anyway it's very rarely teenagers use a mobile phone for it's intended purpose. They are either busy being text jockeys or talking to it on their hand like they do on X-Factor. And don't forget that they have a hands-free apparatus for your car. So it'll be no great los...
