Re[2]: Natural Thorium

[Tad_Blanchard@ccmail.gsfc.nasa.gov]

I recently analyzed a newer type lantern mantle and didn't find any 
Thorium.  They must have changed their formulation.

You can make an outstanding image of a Coleman (R) latern mantel in about 
20 minutes on the technitium-99m photopeak.  Oral legend has it that the 
photons come from thorium.  Apparently, the idea is to spike cub scout 
latern mantels so the ash becomes ionically charged and does not drop into 
the latern base.  Instead, the ash is upposed to float into the atmosphere 
of your 10 year old's tent for filtering by the lungs.

So why is the FDA so hell bent on disabling nuclear medicine in the USA?
