Our desire for new technology grows every year but new innovations can also lead to concerns about possible health effects. In the 1970s microwave ovens were linked to health concerns, in the 1980s the debate turned to VDUs, then in the 1990s concern was voiced about mobile phones and their base stations. The debate is currently focused on concerns about exposure to radio signals from wireless computer networking (WiFi).

Satellite navigation systems, broadcast radio and television, mobile phones and WiFi all use radio signals transmitted through the air. The number of radio transmitters in the community and in homes has increased markedly over recent years.

At the Health Protection Agency's (HPA) fifth annual conference in Warwick a symposium will consider what is an acceptable level of exposure to these radio waves without them being a risk to our health? Dr Simon Mann, from the HPA's Centre for Radiation, Chemical and Environmental Hazards will present 'Measuring Radiowaves in the Environment' on the first day of the conference.

Dr Mann will explain how radio waves are measured to what use the results are put. He will show the different types of equipment that can be used to measure the strength of radio signals in the environment. Typical results will be shown and a live demonstration of a spectrum analyser, used to measure the strength of radiowaves, will be given. Dr Mann will use the equipment to measure the signals from delegates' mobile phones.

Dr Mann says: "The HPA, in conjunction with expert groups, has investigated and advised people on what impact radiowaves may have on their health. Internationally, health authorities such as the World Health Organization have done the same. Extensive research has been carried out on the biological effects of exposure to radiowaves and, although there are some remaining uncertainties, there is a sound scientific basis already used for restricting our exposure to them."

Advice provided by the Health Protection Agency has been used to develop health-related studies.

The Health Protection Agency ' s annual conference takes place at Warwick University from 17th to 19th September. Further information can be found at the conference website at http://www.healthprotectionconference.org.uk.
