I won't send the earlier messages, but I believe you can get the "gist" of the earlier discussion.... Anyone who might want the whole discussion, I'm sure that Marjorie would share it with you.... Cheerio..... (As I said, I'll be sending the group one more message on this -- my "footnote" message to NIEHS, sent a number of months past....)

And because the separate wires for each of the three phases have been brought close together, the strength of the electric field between wires will be greater than would have been the case if these same wires were overhead. So buried power lines will expose people not only to the RF field (which WON'T cancel) that lies close to the current-carrying wires, if there is power line carrier on these wires, but also to the ELF (50/60 Hz) electric field that exists between the wires that are at different potentials. The RF field I feel certain IS hazardous to health. The degree of hazard to health posed by the ELF electric field is not definitely known, but I would judge it to be considerably LESS hazardous than the RF field due to power line carrier. (The very earliest studies of bioeffects looked at electric field effects; none were found. But I have not reviewed this literature carefully, so I don't want to make any definite statements about it, other than the very general one that investigators finally got tired of looking for electric field bioeffects that never made an appearance. I do think it is possible that there may be subtle bioeffects from electric field exposure yet to be discovered.) Just one more point: When wires are overhead, the ELF electric field is taken to be that between the wires and the ground. When these wires are buried underground, THAT electric field vanishes from above ground, leaving only the field BETWEEN wires to be experienced at the ground level. This between-wires electric field is NOT experienced at ground level from overhead wires. So it is important to recognize that the ELF electric fields are not at all the same in the two cases. -- Marjorie ======================================================= rbeavers@llion.org wrote: > Marge: > > The "electrical 'field' component" will still be there.
