Health
The intensity of the electromagnetic fields that are produced by the antenna installations of T-Mobile remains far below the standards that are laid down by the international guidelines. As long as these guidelines are maintained, the World Health Organization is convinced that there are no health risks involved with mobile communication.
Safety
T-Mobile works under strict safety guidelines in the development and maintenance of its network. These guidelines stem partly from the National Antenna Policy and are set out in the T-Mobile code of conduct dealing with safety at work, for example.
