For Matt

I think that Thorium is a really cool element.  One thing that makes it so amazing is that it is the most energy dense element in the universe.  It also has a half life of 14 billion years, which is the same thing as saying that it is very weakly radioactive.

"Man, I wish I had some thorium," I was thinking to myself the other day.  Then, it dawned on me, "I do have some thorium."

Don't rush to call the federales just yet.  The thorium is in the form of thoriated tungsten TIG welding electrodes.

You can read about them here.  The 2% thoriated electrodes have a red stripe on the end.

Here is a photo of some thoriated tungsten TIG electrodes and a Geiger counter.

Next,  is a video clip of the geiger counter measuring background radiation.
 

Lastly, are two clips of the thoriated tungsten TIG electrodes next to the Geiger counter.


 

As you can see, they are very weakly radioactive.  Cool, huh?
