Wireless technology is a feature of some devices we use at home and in the community. Radio waves are used to transmit signals from one device to another.
Some common home applications include wireless telephones, computer networks, baby monitors, headsets, thermometers, switches and home security alarms. What all these applications have in common is that they transmit weak signals that diminish with the distance, so the resulting exposure is usually far below the Authority’s reference values.
The Swedish Radiation Safety Authority has measured people's exposure to radio waves in different arenas in society. The results show that even if we add up the exposure to different kinds of transmitters, the total exposure to radio waves is low. Consequently, in the assessment of the Authority, no health risks are posed by exposure to base stations for mobile telephony, wireless computer networks nor similar transmitters.
However, when it comes to use of mobile phones, there is a slight suspicion that this has an impact on human health. This factor has led to the Swedish Radiation Safety Authority's conclusion that reducing unnecessary exposure is justified. This can for example be done by using hands-free equipment or the speakerphone setting.
The role and responsibilities of the Authority
The Swedish Radiation Safety Authority performs measurements, evaluates research findings in the field, gives advice, and issues recommendations and regulations. The Authority's mandate encompasses the general public's exposure to wireless technology, whereas the Swedish Work Environment Authority's mandate encompasses corresponding aspects in occupational settings.
