Mobile phone radiation and 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[update], there were more than 2 billion users worldwide). Mobile phones use electromagnetic radiation in the microwave range, and some researchers[1] believe this may be harmful to human health. These concerns have induced a large body of research (both epidemiological and experimental, in non-human animals and 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, based upon the consensus view of the scientific and medical communities, states that cancer is unlikely to be caused by cellular phones or their base stations and that reviews have found no convincing evidence for other health effects.[2][3] The WHO expects to make recommendations about mobile phones in October 2009.[4] Some national radiation advisory authorities[5] have recommended measures to minimize exposure to their citizens.
