Just to note a personal experiance -- took a field meter home and looked everywhere for fields -- worst was next to an old bedside clock radio with a motor that flipped the numbers on a mechanical display -- next was within about 6 inches of the TV face, but nothing anywhere else...........

It has been debated in local newspapers around here because of the "Marcy South" line that runs through our area on its way to New York City. My EMC professor (yes EMC is a class at SUNY Binghamton) showed us a graph of a common household. The 60Hz fields near your average kitchen stove are much higher than the fields that you would experience under a large power line. Many people forget that proximity can make up for raw field strength. It would be interesting to know how much 60Hz I'm bathing in right now as I type at my computer. Dave, do us a little experiment. Measure the 60Hz fields right at your chair where you sit all day in front of the computer. How would that compare to a power line?

A friend and I drove to a house he was interesting in buying so that we could measure the 60 Hz magnetic fields (it is near some big power lines). While driving I switched on the equipment and was surprised to measure such a strong mag field from the dashboard. I can't remember the actual magnitude but it was high.
