Re: Info on radium paint?

[CLEMENTC@crl.aecl.ca]

My office deals with the occasional radium painted dial.  The radionuclide
is Ra-226.  I've never worked out the concentrations, but the most active
dial I've seen reads about 1 mR/h on contact.  Interestingly, the dial
is on a radiation detection instrument (but the scale is in R/h, so
one mR/h would hardly show up).  As for manufacturing techniques, the
radium paint was simply painted on by hand.

Hope this info is useful.
