Trying to make stuff glow with radiation

In preparation for another video, I'm experimenting with materials that might scintillate under X-Ray, I had some uranium glass and Zinc Sulfide laying around, so I thought I'd give it a try before I go and pay real money for a LYSO crystal. Shown in this video are both a Radaicode 101 and Radex Geiger counter. Update, I manged to find a LYSO crystal and make that glow:    • #LYSO crystal Under Xray machine
