For many years questions have been raised as to whether radio waves might have an effect on the health and safety of users or the general public. There has been a lot of research on the subject over more than 50 years. This research has looked at various analogue and digital signals, power levels, frequencies and modulations, including those used by TETRA. Research has been reviewed by independent panels of scientific experts and standard setting bodies around the world such as the Health Protection Agency (HPA), the International Agency for Research on Cancer (IARC), the International Commission for Non-Ionising Radiation (ICNIRP) and the World Health Organisation (WHO). In short there has been no evidence established that exposure to radio waves within the accepted exposure guidelines results in any adverse health effects. See also our Science and Standards pages for further information.
The exposure guidelines, designed to protect both the public and occupational users of radio technologies, are set by independent expert organisations such as the ICNIRP. The guidelines are endorsed by the World Health Organisation and other authorities around the world. They set limits for exposure, incorporating a significant safety margin, based on extensive reviews of the scientific evidence. Companies that produce radio equipment or build networks must ensure they comply fully with the guidelines through careful product design and rigorous testing. The extensive body of scientific research into radio-frequency emissions, to which scientists continue to add, and which is reviewed regularly by expert bodies and standard setting organisations, provides a sound basis for confidence in the safety of radio technologies, including TETRA.
