What is the latest position on the use of thoriated (2% thorium) electrodes in TIG welding?
(1) Is the usage of these electrodes legal/permitted?
(2) What are the potential health effects?
(3) What are the relevant exposure limits?
(4) What are the substitutes (eg- Ceriated electrodes), and how good are they?

The most of the nuclear industry still uses the 2% for pipe welding. The minute amount of alpha emission was deemed inconsequential.
