Here are a few important facts about mobile phones
5 billion - The number of mobile phones in use around the world.
50% - The 10-year rise in tumours located in areas of the brain most vulnerable to mobile phone radiation.
25mm - The distance that BlackBerry recommends keeping its phones away from the body.
16 - The age under which people are advised by the NHS to keep mobile use to a minimum.
Most (97-99%) of the radiofrequency electromagnetic energy RFE emitted by mobile phones is absorbed in the hemisphere of the brain where the phone is held, with 50-60% absorbed by the temporal lobe2 which is situated closest to the ear.
Brain cancer rates in USA have increased by 25% since 1975. In 2001, 185,000 Americans were diagnosed with some form of brain cancer. A grade four brain tumor can grow from the size of a grape to tennis ball size in just 4 months.
Always read the small print: Official advice
Research is split on whether mobile phones pose a health hazard or not. Buried in the small print, companies already issue precautionary advice.
BlackBerry
BlackBerry's booklet states: "Use hands-free operation if available and keep the BlackBerry device at least 0.98in (25mm) from your body (including the abdomen of pregnant women and the lower abdomen of teenagers) when the BlackBerry is turned on and connected to the wireless network... reduce the amount of time spent on calls."
iPhone
The iPhone4 guide says: "...when using the iPhone near your body for voice calls or wireless data transmission over a cellular network, keep it at least 5/8inch (15mm) away from the body, and only use carrying cases, belt clips or holders that do not have metal parts and that maintain at least 5/8inch (15mm) separation between iPhone and the body."
UK Department of Health
A spokeswoman says: "As a precaution children should only use mobile phones for essential purposes and keep all calls short. We keep all scientific evidence under review."
