The electromagnetic energy from the power lines will drop very fast
(square
of the distance? wish I still had my books). Some basic information on
radiated waves is here: http://www.fas.org/spp/military/docops/afwa/U2.htmhttp://hawkins.pair.com/eRadiation.htmlhttp://www.arrl.org/tis/info/whyantradiates.html
adalbert goertz remarks:
The electric and magnetic field gradients for a cable/power line
is not that fast and NOT like the inverse sq of the distance, but rather
inverse LINEAR distance. However, the magnetic field drops down to less
than that of the earth magnetic field (0.2 Gauss) except in the immediate
area of the power line. None of this causes a Geiger counter to click.
So, power lines do not present dangers to anyone close to the ground.
(meaning farther than 5 yards from the power line).
