Hello all, I am leaving tomorrow for vacation and may not get the
replies to this for a week, but here goes...

I have had many mixed feelings regarding the "health effects" of HF
current through ones body. Surly, we need to discourage it because of
the most obvious IDLH (immediately dangerous to life and health)
conditions that will be present during such an act. But, does anyone
have any ready references to scientific literature that may demonstrate
deleterious effects upon mammals? In my experience the energy is
dissipated very locally. And this has been with work with VTTC's well
over 2 KW (enough energy to melt a framing nail in short order). I would
think that currents bellow 100-200 KHz certainly may distribute the
heating damage deeper into the tissue, but has anyone modeled the
heating effects in tissue? My thinking is this is a very interesting
area of discussion, in need of further elucidation.

Just my thoughts,

David Trimmell

By the way, just because you *can't* feel any damage being done to you,
doesn't mean there is no damage being done to you.
