Finding out more about other issues

This website deals with the electric and magnetic fields produced by the use of electricity including the electricity transmission and distribution systems - power lines, substations etc.

We recognise that people often have other questions about power lines and substations.  We can't provide detailed or authoritative answers to these non-EMF questions but we provide some pointers here to where you can find out more.

• Wayleaves and easements - what are the legal agreements that allow power lines to be present on private land?
• Safety clearance distances - how close is it safe to get to an overhead line? Are there activities it's not safe to do close to a power line?
• "Danger of death" notices - does this mean pylons and substations are unsafe?
• Audible noise - should power lines and substations produce noise?
• GPS - do power lines interfere with Global Positioning Systems?
• TV and radio interference - should a power line interfere with TV and radio?
