at just what power intensities should we begin to worry and expect
damage? One-watt, ten-watts, one-hundred-watts, one-kilowatt,
multi-kilowatts?

There are guidelines available for this from the FCC -- it's a
function of exposure time, frequency, and of course power. The
numbers have been around for many decades now, and you might recall
some questions about it showing up on your license exam.

That being said, I'm not suggesting more studies aren't in order, just
that many people have a very mistaken impression that there aren't
already many, many studies that have tried to ascertain "safe"
exposure levels to RF. (Another thing most people aren't aware of is
that cell phone antennas are usually specifically designed to *not*
radiate "into" the head. Ham radio antennas usually aren't, yet you
see plenty of folking holding up a 5W HT to their mouths...)

Some differences are that HT conversations tend to be a lot shorter.

I'll bet my XYL spends 4 hours a day on various wireless and cell phones.
I know some who spend more. But they are convenient, they are handy. You
can walk around with them and do other things whil you are doing it. Its
a "big help" in her business.

That's okay, she thinks I'm nuts with my concern for cellphone use also.
Hopefully I'm wrong.....


Decades of living with "safe radiation levels" established for atomic
elements sources which were "re-evaluated" to downward levels many
times has made me a bit more cautious than yourself ...

We've revised them downward because we've found out more about them.

Life today is far, far safer overall than it was decades ago.

Right. Its a learning process. We've found out about a lot of things
that can do us damage.
