hum from nearby high-tension wires?

Two things about so-called 'harmful' EMF - 1) The fields decrease at a square of the distance, i.e. if you double the distance away from the line, the field intensity goes down by 1/4, triple the distance 1/9, etc. So while there is detectable electromagnetic radiation below the lines, its pretty weak at ground level. 2) If EMF from power lines causes cancer,etc., why isn't there any epidemic among power company Lineman (there isn't). And no, I don't work for an electric utility. But there is No solid proof of EMF from power lines being harmful (unless, of course, you come in contact with one and are grounded)...
