+I've heard people asking this same question before (ie. do high voltage
+lines threaten health). I doubt it. The current flowing through the line
+is a.c., yes, and that means there's a constantly changing electric field.
+As you know, this means that the lines are giving off electromagnetic
+radiation. HOWEVER, in North America a.c. only alternates at 120 Hz. This
+means that the radiation being emitted is only 120 Hz. That is extremely
+LOW, and is probably not a threat to anyone. Mutations due to exposure to
+radiation are usually only found with much higher frequencies (ie. long
+term exposure to UV light, gamma radiation, etc..).

+I'd also guess that power lines can't harm your computer.

AC in North America is <60 Hz>, not 120. (This seems to be real good
for keeping electric clocks on time)

Most nations have either 50 or 60 Hz, though I once lived in the Canal
Zone in Panama, where they had 25 Hz, and it was not too difficult to
detect the "movie projector flicker effect." First thing I did wrong
was to plug in my electric shaver and burn it up.
