There is a nice chart for MPE limits. However, there is no information given
for frequencies below 300kHz. Does anyone know what the MPE limits would
be for both electric and magnetic field strength at 80kHz?

I'm going to make a guess on this. At pretty low f, absorbtion starts to
go down. I know they communicate with submarines with RF carriers around
12-14 kc because ocean water is almost transparent. Only when absorption
of RF gets high then there are "bioeffects" (mostly thermal, but there is
controversy about non-thermal effects). Others here might be able to be
more specific for that range 14 khz to 300 khz.

Thanks,
