Re: Thoriated Welding Rods

Jay --

There is an IAEA committee working on the problems of Th in industry 
right now, so you may want to contact them.  I don't know who the IAEA 
scientific secretary is, but when in doubt, I contact Dick Griffith, who 
is very knowledgable and very helpful.  The problem is discussed in depth 
in the ancient but still excellent book put out by the AIHA about 40 
years ago entitled "Thorium".

Anf, if you've read this far, probably the best source of information 
would be the state radiation control group.

Finally, since I didn't mention it in class, I won't rescind your "A+".

Warmest regards,

Ron Kathren
