Radiation in relation to mobile phone use The release of this WHO statement prompted many people to call for a 'precautionary approach' to mobile phone use. However, in May 2011, the World Health Organization (WHO) classified RF radiation as ‘possibly carcinogenic for humans, based on an increased risk for glioma, a type of brain cancer’. Intensive international research has found no conclusive or convincing evidence that mobile phones are damaging to health in the short or long term. Research into mobile phones and health risks There are concerns that the low levels of RF radiation emitted by mobile phones could cause health problems such as headaches or brain tumours. If RF radiation is high enough, it has a ‘thermal’ effect, which means it raises body temperature. Mobile phones communicate with base stations using radiofrequency (RF) radiation. It is important to understand the risks and possible effects of mobile phone use, and make up your own mind about how you use your mobile phone. Because so many people use mobile phones, medical researchers are concerned that any associated health risks, even small ones, could cause significant public health problems. Because mobile phone use is so widespread (it was estimated in 2011 that there were around five billion mobile phone users), public concerns about the possible health effects of mobile phones receive a lot of coverage in the media.
