In 2006, RATP set up a special unit under the Monitoring Commission that aims to provide a health, regulatory and scientific watch. We carry out actions to protect passengers and staff from exposure to electromagnetic fields and to inform them of the risks.
We do this in collaboration with ANFR, the French national frequency agency. We also monitor the related research and conclusions of ANSES, the French health safety agency, and apply the precautionary guidelines set by the national authorities.
RATP also conducts measurement campaigns to ensure that its installations respect applicable standards. Regardless of the configuration, notably for mobile devices as part of the deployment of 3G/4G mobile services, the level of emissions measured in the RATP networks is much lower than current regulatory thresholds.
What precautions should passengers take?
Favour areas with good reception : avoiding telephoning in sectors with poor network coverage (inside vehicles or elevators, for example). To maintain transmission quality, your mobile phone increases its transmitting power, which increases your level of exposure.
Tip: You know you are in an area with good reception when the maximum number of bars is indicated on your mobile device.
Keep your mobile device at a distance : to limit exposure to the head, use a hands-free kit (earplug).
Avoid calling when travelling at high speeds : when traveling at high speeds (in trains, for example), your mobile device enters into contact with a succession of relay transmitters, and will usually switch to maximum transmitting power to search for the next one.
