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, and expects to make recommendations about mobile phones in 2007¿08. However, some nations' radiation advisory authorities, including those of Austria,[1] Germany,[2] and Sweden, 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. Still, the use of "hands-free" is not recommended by the British Consumers' Association http://www.Cellphonelies.com
