Isn't radium radiation Alpha? I had a radium-dial watch in the 1950s 
that tripped detectors while visiting a nuclear power plant. I was told 
it was harmless -  Alpha - would not penetrate skin. Just don't eat the 
stuff. But I know an old aircraft guy who got into a lot of trouble over 
luminous instrument dials. At one time my race car had surplus 
instruments that had that problem.
