Re: Mg-Th Alloy Production

Dan and list



I attend a conference on thorium in 1994 and presented a paper. I don't know

if the information you are looking for is in the proceedings but it should

be. It was a Commission of the European Communities conference on the Health

Effects of Internally Deposited Radionuclides Conference held on April 18-22

and the proceedings are published as EUR 15877 EN by World Scientific

Publishing.

> I am looking for information on magnesium-thorium alloy production.  I am

specifically interested in any data that might be available concerning the

state of equilibrium of the Th-232 daughter products in such materials.  I

am proposing to assume that, during the process of manufacture (smelting) of

the thorium additive, the daughter products would have been effectively

removed and that any existing material could be 'dated'  based on the degree

of ingrowth.  I would be very interested if anyone has any data on this or

other input on the validity of the this assumption.
