The Coleman Company recently discontinued their "green top" 
thorium mantles and began marketing a Gold Top mantle The new 
mantle contains (non-radioactive) yttrium instead of the thorium. 
Thorium mantles can still be purchased at Sears and Target 
stores under brand names "Century Primus" and "Greatland 
Camping". I'm told mantles of foreign manufacture purchased 
at surplus stores are likely thorium-based, as well.

If you can't find them, here are some addresses:

"Century Primus", Century Tool & Manufacturing Company, 
P.O. Box 188, Cherry Valley, IL 61016.

"Greatland Camping", WICKS, P.O. Box 645, Taylors, SC 29687
