The Geiger Counter wand utilizes a thin mica window GM tube that allows the detection of alpha radiation as well as beta, and gamma radiation. Operating range is 450-600 volts, the recommended voltage is 500 volts.
The physical dimensions of the wand are approximately .85" diameter and 5.75" long. Approximately three feet of shielded cable connects the wand and a mini din plug.

Geiger Counter Wand
These radiation shields friction fit on the open end of the Geiger Counter wand. Each shield helps to block radiation from reaching the internal GM tube inside the wand.
The shields are useful in performing nuclear tests and experiments.
The Screen shield is an open mesh nylon screen that allows all radiation including alpha to pass through. The paper shield blocks alpha radiation, while permitting beta and gamma radiation. The aluminum shield attenuates beta radiation and the lead shield attenuates gamma radiation. Shields may be purchased separately or in a set.
