Geiger Counter Wands

The GCW-01 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 GCW-02 Geiger Counter Wand utilizes a Glass GM Tube that detects beta and gamma radiation. Anode resistor: 2.2 megaohms. Operating voltage is 400 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.

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.

Radiation shields only compatable with the GCW-01 Wand. 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.
