THIS IS NOT RADIOACTIVE. IT DETECTS NATURAL RADIOACTIVITY IN THE ENVIRONMENT
SEE ALPHA RADIATION! See Po-210 Polonium 210 radiation with the naked eye
This
1.5″ screen is mounted in a cardboard frame for hand holding. Place
radiation source behind screen in a darkened room and view the
scintillations (flashes of light) from the front
NOTE: We now
can make custom size sheets to fit your application, up to 8 X 10
inches. Made onto a crystal clear substrate with excellent optical and
physical properties. Use to make new instruments, line Lucas Cells or
repair Alpha Scintillators. Can be cut to shape with scissors.
Reasonable prices. Call for quote and a custom eBay ad offering directly
to you.
ATTENTION Physics / Science Teachers and Instructors
PHYSICS DEMONSTRATION,
Used to make:
Spinthariscope
Geiger Scope/ Scintilloscope free instructions included
PhotoMultiplier Tube Alpha scintillation detector
Lucas Cell ( larger custom sizes placed on eBay at your request)
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 $1000.00 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.
