Re: More on Thoriated Tungsten

You really don't want to be using the thoriated types in Tesla work. 
They do slowly oxidize and release fine particulates of radioactive
thorium oxide dust into the air, which you really don't want to breathe
in as the particles can settle in your lungs and cause lung cancer.

IMHO, since non-radioactive rods with cerium or lanthanum are readily
available, I see little point in trying to use the thoriated versions.
