EXTREMELY LIMITED QUANTITIES OF THIS ITEM!!**  There is now a worldwide shortage of Silver activated Zinc Sulfide.
Special Polycrystaline Silver Activated Zinc Sulphide viewing screen with Crystal Clear backing, mounted on cardboard frame.
The green glow can be viewed via a magnifying eyepiece, or direct optically. Individual scintillations can be made out with 10X magnification and a good Alpha source, experiment with the distance form the source to the screen for different effects.
Add a PhotoMultiplier Tube to create a super sensitive Alpha scintillation detector
Same screen material as used in 00.00 Homeland security detectors, and industrial contamination detectors-Special material on the screen radioluminesces upon being struck by the Alpha particles from a radioactive source
As with all Spintahriscopes,best viewing is in a darkened room, and time must pass for the eyes to adjust to the dark.
Just like we use here at GEOelectronics. Mat Hazzard, the radioactive Pumpkin is NOT INCLUDED.
