However, they are harmful if released inside the digestive tract, or inside the lungs, where they act as a carcinogen..Thorium oxide is, therefore, a low level radioactive material which may give rise to both a small external radiation hazard and an internal hazard from ingestion or inhalation. How do you beat Thorian? Thorium increases the electron emission quality of the electrode, which improves arc starting and allows higher current carrying capacity. One is the tungsten electrode that creates the arc and is mostly non-consumable. There are a significant number of lenses produced from the 1940s through the 1970s that are measurably radioactive. Technically both are radioactive. Can you weld aluminum with a red tungsten? Aside from thoriated tungsten electrodes, other electrodes, TIG filler rods, and arc welding rods do not have hazardous ingredients at all.
