Study Design

Prior to the Airwave Health Monitoring Study, no epidemiological or occupational studies had looked into the possible short-term or long-term health risks associated with TETRA exposure.

Some studies have investigated the use of conventional mobile phone use and health, but the results so far have provided no persuasive evidence of any adverse health effects associated with mobile phone use.  However these studies have often been limited by insufficient numbers of participants and lack of detailed information on mobile phone use.

Relatively few occupational studies have examined the relationship between microwave radiation and health, and no large-scale study has ever been established among the police force in the UK.

Overall most studies to date have not found any significant health effects associated with the use of GSM digital mobile phone technology.  However health effects in relation to exposure to TETRA technology has not yet been investigated.  Hence, the current Airwave Health Monitoring Study aims to investigate any possible impacts of TETRA on health by looking at TETRA exposure and subsequent health among police officers and staff.  This study aims to improve upon previous study designs by including ; a longer period of follow-up with sufficient numbers of participants and  better classifications of exposure information.

For cancer and most other chronic diseases there is usually a long period of time between exposure (to some environmental hazard) and incidence of the disease.  In 2001, the National Protection Board’s (NRPB) Advisory Group on Non-ionizing Radiation, pointed to the possibility that “microwave radiation from mobile phones (including TETRA) might carry risk of cancer that becomes manifest many years after first exposure or that relates to intense exposure over several years” (AGNIR 2001, p.35).  In order to address this issue effectively, a long-period of follow up is needed to allow for the latency between exposure and disease incidence.  This is what the Airwave Health Monitoring Study aims to achieve, by conducting long-term monitoring of its participants, so that disease incidence can be assessed for its relationship to current TETRA exposure.
