The comment was probably made in jest, but cancer in rats bears little
resemblance toward humans. Often the animals are exposed to high
concentrations the humans. I take rat poison as a blood thinner, yet
the same dose would be fatal to rats, so I have little faith in what
some chemical does to small animals.
As a kid, I had a strong interest in chemistry. I had two pint bottle
of mercury that I experimented with. At age 50, I earned a Bachelor of
Science degree in CS, not CIS and did well enough to become a graduate
assistant for my masters, so apparently the mercury had little effect.
That mercury is bad stuff there is no doubt.
Lead OTOH should not be ingested by infants, but for adults? When I was
shooting competitive, I was going through about 500# every 2 months.
I remember the freight depot calling my folks and saying, please have
him come and take this stuff away.
As a teen, I dynamited stumps and rocks for the neighboring farmers. If
a farmer found some old dynamite, they'd call me to get rid of it. What
I didn't like was disposing of old 60% sticks that were in a puddle of
oil, because that wasn't oil. I still own the farm, but I doubt I'd
even be able to get a powder license, nor do I have need for one. A. I
used a lot of it.
But getting to ham radio and non ionizing radiation.. For a good many
years, I worked with RF heating generators in the 100 to well over 200
KW within a few feet of the heating/load coils. We as hams have to
observe some rather stringent limitations. I had a pair of 12L Yagis at
130 feet. When running FM. or AM, I was limited to only a couple hundred
watts. My tribander at a little over 100 feet had to be that high for
the protected area. A 6' individual was just under a foot from
radiation considered too high, yet people with cell phones and hams with
a 5W HT exceed these limitations regularly,
We know, non ionizing radiation causes heating, but from what I've read,
the limits are arbitrary and in Europe they have much lower allowable
limits. How do they determine what is really dangerous and then cut
that to some limit.
My degree is in CS with a math minor. Lots of calc based physics and a
couple years of chemistry.
I do think society over reacts to many chemicals and many of the alarms
do come from California.
That some chemicals causes a reaction in small animals often bears
little reality as to what it would do to humans.
Many of these limits sound more like propaganda to me.

On what basis do you say that? That sounds like uninformed propaganda
to me. And are you saying that stuff that causes cancer is OK? Is it
OK to put lead and mercury in places where humans can injest it?
My wife and I are both scientists, she in the area of human biology
and me an EE. I DO believe in science and the scientific method, and I
do NOT repeat uninformed gossip.
