The ICNIRP guidelines are based on decades of research into electromagnetic fields and human health. They establish the point at which adverse health effects are known to begin due to the heating of tissue and set limits 10 to 50 times (5000%) below that as maximum exposure levels for workers and for the public respectively. These limits therefore provide a large safety margin for all members of the community including children.
As the World Health Organization states:
The exposure limits for EMF fields developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) - a non-governmental organization formally recognised by WHO, were developed following reviews of all the peer-reviewed scientific literature, including thermal and non-thermal effects. The standards are based on evaluations of biological effects that have been established to have health consequences. The main conclusion from the WHO reviews is that EMF exposures below the limits recommended in the ICNIRP international guidelines do not appear to have any known consequence on health.
