I switch to Lanthanated Tungsten electrodes for the very reason you
mentioned. However I have recently purchased a very sensitive Geiger
counter capable of detecting Alpha particles (what Thorium emits) and
saw no difference from background radiation when in close proximity to
the Thoriated rods. I would still advise precautions if using Thoriated
rods but the risk is probably very very low especially since we are not
regrinding rods daily as a wielder might.

I still have a number of extra 3/16 by 8 inch Lanthanated Tungsten
electrodes available for $10 each. Should anyone be interested contact
me off list

Greg,All,  Today I talked to the fabricators about grinding thoriated
rods.
Their reply: you MUST,MUST either "wet grind" or wear well fitting mask
approved for radioactive particulates.They "wet grind"(both their rods
and
mine). SM
(perhaps I should dig up my geiger counter and investigate,if it still
works)
