I had some dealing with thoriated prism lenses out of aircraft sextants over
ten years ago.  It was in the melt of the glass rather than being in a coating.
 There was no significant hazard unless the glass broke and controlling broken
glass is, of course, easy.

I'm not sure who made them, I think it was either Baird Atomic or Nuclear
Chicago made them.

I could never find out why thorium was needed in the glass.

The original message is still not getting out.  Maybe this war story will be
useful and maybe it won't.
