Electromagnetic fields from power lines, electric appliances, cell phones and such are suspected to put risks on human and animal health. Although scientific studies do not show an operational consensus, the precautionary principle should lead us to limitate those fields as much as possible. Exposure to fields from cell phone antenas is particularly worrying since they operate in urban areas at high power.
CENELEC has established the technical committee CLC/TC 106 on "Electromagnetic fields in the human environment" and its Working Group 1 "Mobile phones and base stations" following a mandate from the European Commission. Their task is to draft standards defining the requirements to protect human beings from hazardous effects which may be caused by exposure to electromagnetic fields emitted by base stations.
