Grinding tungstens

[Charred fingers]

I don't do tig welding but this may be of interest to those that do. Someone I know got a book on welding for Xmas and in the section on tig it said that the dust generated when grinding tungstens is mildly radioactive anyone heard this before.

Only by ingestion, so along as you don't eat any you should be OK

Yes, Thoriated tungstens are mildy radioactive. Like the glowing hands on old watches.

Really only a danger of breathing the dust. There are other types available: Lanthaited and Ceriated,
