en.wikipedia.org/wiki/Tungsten

Tungsten is a chemical element with symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, from tung sten "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. It was identified as a new element ...

Thoriated Tungsten Radioactivity. Background. For quite some time, tungsten manufacturers have added an oxide to pure tungsten to improve the arc starting characteristics and the longevity of welding electrodes. While 2% thoriated tungsten has been the most commonly used tungsten material for many years, this ...

About a dozen radioactive isotopes of tungsten are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation. Radioactive isotopes are produced when very small particles are fired at atoms. These particles stick in the atoms and make them radioactive. None of the radioactive isotopes of ...

Apr 19, 2012 ... The concerns arise from the fact that the element thorium is radioactive. On this basis, many organisations have evaluated alternative tungsten types to see what changes in performance they would see by transitioning to non-radioactive tungsten. The radioactivity problem. The Thorium used in 2 per cent ...

Um, I would make sure you have ventilation, some of the high dollar tungsten grinders actually catch all the particles that come off, but they're pretty costly. I personally don't even use Thoriated anymore, Ceriated is the way to go. It works just as well as Thoriated, it isn't radioactive, and here at least, ...
