High-Voltage Power Lines - How far away is safe???
wang...@wongfaye.com
Assuming that they are bad for your health, how far away is safe???
300 yards? 600 yards? .5 mile?? 1 mile??
Thanks.

I seem to remember a MythBusters episode where they tried to create a huge
coil of wire to capture electricity from overhead power lines... they had to
move the coil very close to the lines to get anything usable in terms of
voltage.
In other words, the electromagnetic radiation from power lines diminishes
very rapidly over distance.
What I would be more concerned about, however, is the corona discharge
creating negative ions that cause excessive particle deposition in areas
downwind of high-voltage power lines. Think along the lines of those Ionic
Breeze air purifiers, magnified by about 10 million times. Have you ever
looked at what is deposited on the Ionic Breeze capture bars? It's a thick
black gunk... particle deposition. Except with power lines, that gunk is
ending up on your skin and in your lungs.
Here's a link to more info:

Two quotes that are particularly disturbing:
"An increase of charge density downwind of power lines is well established
and can be measured at distances up to several kilometres. The ion clouds
charge pollutant particles that pass through them. These particles will
already carry some charge because of the naturally occurring ions that exist
in the atmosphere but it seems likely that in some regions this will be
increased even at ground level as a result of corona discharge."
"The presence of corona ions could influence the uptake of pollutants by
increasing their deposition in the lung or on the skin."
