[ RadSafe ] Thorium Lamp Mantles

[Ted de Castro]

Does anyone know where there may be a source of the Thoriated - ie. 
radioactive - lamp mantles.

I need a few check sources and only have 2 hot packets left.

The Coleman branded ones have not been hot for some time - but I just 
went shopping around and even the imports I found are cold.

A packet of No Salt is not quite hot enough to work well and a smoke 
detector source is too hot and a bag of fertilizer too large.  AND - I 
am NOT breaking up my Fiesta Ware!!!
