Question on -- United States Mint coin security feature
Arizona Coin Collector
I was curious to know if the dollar coins that are now
being minted by the United States Mint, may have
been treated to be a little radioactive? This could be
a security feature to the coins.
Has anyone check out the current coins that are
minted by the United States Mint with a Geiger
counter? It could be the same amount or level
that you would find on a face of and analog watch.
If someone can get a Geiger Counter, and check
out the level of radioactive level, I would love to
know.

I don't have a Geiger Counter handy, but I think that's quite
unlikely.
The current dollar coins are comprised of copper, zinc,
manganese and nickel. None of those elements have any
naturally occurring radioactive isotopes, so adding any
radioactive markers would either require addition of a
another element, or neutron bombardment of one of the
existing ones.
Of the candidates, only Nickel has a reasonable candidate
isotope. But there are three problems with that idea. The
first is that neutron bombardment is expensive. The second
is that bombarding natural Nickel also produces hazardous
Nickel-63. Finally, Nickel raises enough health objections
even in stable form.
So in summary, I don't see either the need nor the method for
adding such a security feature.

Now there is a case for dumping your change in a jar instead of carrying it

Sounds like it was concocted by the same people who said that
fluoridization of the water supply in the 1950s was a Commie plot to
pollute our precious bodily fluids.

I'll be content to point out that since they put fluoride in our water,
the USA has been subjected to runaway inflation, a loss of its stature
in the world community and a complete loss of the sense of purpose the
country used to have.
Our precious bodily fluids are, however, still intact!

Nah, the fluoride didn't do that. It only made our teeth glow under
ultraviolet light. It's the SeKriT pOISON stuff they're putting in
the chemtrails coming from airliners that is making us morally weak
and economically stupid. With 15,000 flights a day using an average
of 2.5 engines per aircraft in the commercial fleet, and figure
they've been doing it since the 1970s - you do the math. I would,
except that I live in the flight path of an airport so 2 + 2 = 3 is
about the limit of what my math skills can handle nowadays.

We were beatniks ten years before that. We didn't take drugs or encourage
free sex-- we just drank expresso coffee, grew goatees, read profound
poetry, and wore berets. Latter-day hippies were just beatnik wannabe's who
never bothered to read the instructions. Some today may say us beatniks
missed out on the fun.

Irradiated Dimes - (1950s, 1960s)
During the 1950s, the Oak Ridge Graphite Reactor
was the world's single largest source of
radionuclides, and the availability of these
radionuclides revolutionized the field of medicine
and many branches of science. The impact was no
less great in the industrial sector. Radionuclides
were produced in several ways, but neutron
activation was perhaps the most important. The
purpose of the dime irradiator at the American
Museum of Atomic Energy, located in Oak Ridge,
Tennessee, was to provide a dramatic demonstration
of the principle of neutron activation. Today, the
museum is known as the American Museum of Science
and Energy.

I have one of the Irradiated Dimes from the 1964-5 World's Fair,
purchased, IIRC, from Ken Barr in 2003. In the link you cite, you'll
notice that the author could not detect any radiation in the samples.
They also stopped the program after the switch to cupro-nickel
coinage, but whether that was a coincidence of timing or due to the
dangers of irradiated nickel I can't say.
"Tagging" coins would require a longer irradiation and for any coin
which actually circulated they'd have to create a lot more of them.

check it out. Using a military surplus AN/PDR-27R RADIAC meter on the
most sensitive setting, I put the probe over $10 worth of presidential
dollars. Nothing other than normal background radiation.

Looks like you beat me to it. I had some down time in lab today and
tested out a John Adams dollar and a 2000 Sac. No detectable
radiation above background for either coin, from which we conclude
either a) the coins are not radioactive, or else b) there is so much
background radiation in Baltimore that the emission from coins can't
be detected.

Or c: both of the coins you tested were counterfeit. :)
