I have not investigated the solar equivalents - but it would be
interesting
to see what kinds of various continuous RF sources are around,
and just how much reaches us from these various sources -
And yup - same bio results here -
I've been about HF, VHF, UHF and microHF ?
and have loss of head covering, enlarging of the frontal area,
loss of stock portfolio equity, loss of positive attitude,
and enlarging of the stacks of books & articles -
