Hi Phil + Radsafers,
We at the CNS (Canadian Nuclear Society) have demonstrations which
more-or-less follow (with some variation depending on the type of audience,
time available, etc.) those outlined in the pdf document posted at
http://www.cns-snc.ca/ecc/ionRadWorkshop-1998Apr16.pdf
<http://www.cns-snc.ca/ecc/ionRadWorkshop-1998Apr16.pdf>
I have recently moved from Chalk River to Montreal, so I had to re-assemble
a demonstration "kit" similar to the one we had at Chalk. One of the more
difficult items to get is dry ice (for the cloud chambers), but usually you
can get some from a local university chemistry department or possibly a
large hospital, if you can find a person willing to help.
The acquisition of small radioactive mineral specimens turned out to be
relatively easy, since you can get those from some minerals
collectors-dealers, if you know what to look for (a colleague recently
posted information on uranium-containing minerals on his web site at
http://www.ncf.carleton.ca/~cz725/cnf_sectionG.htm#u-th
<http://www.ncf.carleton.ca/~cz725/cnf_sectionG.htm#u-th> ....its easier
to get such rock specimens within your country, than trying to ship them
across the border).
Kids really like the bubble detectors -- you can see & hear things happening
- -- and due to their superficial similarity to fission tracks in crystals,
you can use them to explain the technique of fission track dating (the
detectors are available at http://www.magma.ca/~bubble/
<http://www.magma.ca/~bubble/> ).
Hope this helps !
Jaro

Subject: radiation demonstrations
Hello, Radsafers,
I seem to remember that some time ago (probably years ago) someone asked
about interesting, instructive radiation demonstrations. I'd like to re-ask
what demonstrations people have seen and used, and add that for my purposes
(radiation training roadshow), I'm particularly interested in hearing about
demonstrations that would be easy to pack up in my luggage and fly to Walla
Walla or wherever.
Thanks,
Phil Hypes
