The Parliamentary Assembly of the Council of Europe passed a resolution concerning EMFs. Much of the detail is concerned with microwaves but there are some references to power frequencies, for example it calls on member states of the Council to:
“8.4. concerning the planning of electric power lines and relay antenna base stations:
8.4.1. introduce town planning measures to keep high-voltage power lines and other electric installations at a safe distance from dwellings;
8.4.2. apply strict safety standards for the health impact of electrical systems in new dwellings;…”
This resolution does not carry any force within member states.
