Mobile Radiation and its effects on health

Mobile phone radiation and health concerns have been raised, especially following the enormous increase in the use of wireless mobile telephony throughout the world (as of August 2005, there were more than 2 billion users worldwide). This is because mobile phones use electromagnetic waves in the microwave range. These concerns have induced a large body of research (both epidemiological and experimental, in non-human animals as well as in humans). Concerns about effects on health have also been raised regarding other digital wireless systems, such as data communication networks.

The World Health Organization has concluded that serious health effects (e.g. cancer) are very unlikely to be caused by cellular phones or their base stations[4][5], and expects to make recommendations about mobile phones in 2007–08.

However, some National Radiation Protection Authorities, including Austria[1] Germany[2] and Sweden,[3] recommend their citizens to minimize radiation. Examples of recommendations are:

Use hands-free to decrease the radiation to the head.
Keep the mobile phone away from the body.
Do not telephone in a car without an external antenna.
