And Peter, acknowledging the truth about your post, and knowing
what your concerns are, the effects of electromagnetic fields on
the scale the average person is subjected to them seems like it is
not a major concern. There seems to be no accurate science
recognizing what is or is not safe. I believe in most cities,
particulate matter in the air, air pollution, is a far greater long
term threat, which seems to be basically ignored.
Oh, I fully agree with you here. The level of electromagnetic fields
we’re exposed to in our normal studios is very mild, and presents no
risk that anyone has been able to reliably demonstrate. It’s useful
to remember that the earth itself generates such a field, as well as
electromagnetic radiation from the sun and the universe itself. It
may be, however, a question of Intensity. While I’ve no qualms living
around and working with normal levels as usually found, I’d have some
second thoughts about, say, building my home directly under the very
high tension lines leaving a power generating plant, and I don’t
think I’d want to mount a permanently ON large Tesla coil in my
bedroom for the cool effects either. Being able to light a
fluorescent tube just by picking it up, without other electrical
connections is just not high on my list of things I want to do all
the time (grin).
My wife is always nervous about any investment that she sees, a
little on my pants or some transferred from a concrete floor by my
shoe to a carpet. There is probably more danger from vacuuming
this investment, as it gets blown out the vacuum exhaust. I usually
do a wet clean up.
If you don’t have a HEPA filter on the vacuum, then likely your
quite correct. And investment before it’s mixed up is less dangerous
that after you’ve fired the flask. I’ve heard (right here on Orchid)
that it’s most dangerous form is such as what’s released when you
quench a flask. The aerosol of steam and powder is too small in
particle size to see floating in the air, but after firing, those
particles are especially dangerous, perhaps more so than the
sometimes larger amounts put into the air when you first mix the
investment. Since Silica in the lungs IS cumulative, I’d say you
simply cannot be too careful with the stuff. But as you’ve also said,
careful is not the same as paranoid. One must live one’s life too,
not spend it in lots of effort worrying. So the answer is to educate
oneself about the materials we use, and their risks, then take the
suitable precautions as best we can, and simply get on with it all.
Obsessing about it won’t improve one’s safety, and is hard on ones
There is more danger of life threatening illness from germs and
bacteria in your kitchen sink and your bathroom then some of the
dangers from our studios. Some studio hazards are cumulative.
Bacteria and germs are not.
What? When did you see my bathroom? Actually, I’m not sure you’re
completely correct here. We live in an evironment filled with the
germs, and our systems have become exquisitely well capable of
dealing with them. In fact the constant presence of the things may
help keep our immune systems properly tuned up. For germs, I don’t
worry about my own house. I worry about what I come into contact with
out in public, where other people may bring me into contact with a
variety of bugs that I might NOT yet be tuned up for. But again,
common sense rules, not paranoia. And for dangers, back to the
kitchen sink, I’d guess the most dangerous stuff there is in the
bottles of varous cleaning agents stored under that sink, not the
germs and stuff in the area, though some unusual molds may be an
exception to that… Oh, and I’d also point out that there may be
some cases where exposure to certain microbes is indeed a cumulative
risk. Some people believe that some autoimmune disorders (such as
diabetes) are triggered by multiple exposures to some such
sensatizing agent. The first exposure sets up an immune response, the
second or some subsequent exposure cause an over reaction. Some
allergic responses also work this way.
Safety yes, speculative peranoia, no.
I fully agree.
