First Thorium-232 Spectrum with Radiacode 103

Using thoriated TIG welding rod tips for weekend science.

Over the long weekend, I decided to pick up some thoriated TIG welding rod tips to do some casual gamma spectrometry with my Radiacode 103. I got some pretty decent results with just three tips over a few hours.

Three thoriated TIG welding rod tips placed against the Radiacode 103 detector.

Neat!
