Geiger Counter Wand

GCW-01 Geiger Counter Wand
The GCW-01 features a highly sensitive thin mica window GM tube, capable of detecting alpha, beta, and gamma radiation—making it ideal for comprehensive radiation monitoring.
- Operating Range: 450–600 volts
- Recommended Voltage: 500 volts
GCW-02 Geiger Counter Wand
Equipped with a durable glass GM tube, the GCW-02 is designed to detect beta and gamma radiation with reliable accuracy.
- Anode Resistor: 2.2 megaohms
- Operating Voltage: 400 volts
Compact & Shielded for Field Use
Each wand is lightweight and portable, measuring approximately 0.85" in diameter and 5.75" in length. A 3-foot shielded cable with a mini DIN plug ensures secure connectivity and ease of use in any setup.
Important Note for Replacement Wands
If you are purchasing a wand as a replacement for one of our digital Geiger counters, we highly recommend sending in your Geiger counter along with your order. This allows our technicians to calibrate the new wand specifically to your unit, ensuring the most accurate radiation readings and optimal performance.

Radiation Shields for Wands

Radiation Penetration Calculator
These precision-engineered radiation shields are designed to friction-fit onto the open end of the Geiger Counter wand, helping to reduce the amount of radiation that reaches the internal GM tube.Ideal for use in nuclear experiments and educational demonstrations, these shields enhance the accuracy of your readings by selectively blocking specific types of radiation.
Compatible exclusively with the GCW-01 Wand, each shield serves a distinct purpose:
- Paper Shield: Blocks alpha radiation while allowing beta and gamma radiation to pass through.
- Aluminum Shield: Attenuates beta radiation.
- Lead Shield: Attenuates gamma radiation.

Sled Isotope Holder
The Geiger counter wand base provides a stable platform to hold the Geiger
counter wand for experiments. The physical dimensions of the base are 2" wide
by 12" long. The length of the base has markings in both metric and imperial.
The sled isotope holder provides a stable and moveable platform for radioactive isotopes 1" diameter discs. The sled isotope holder is available in two sizes:
One that holds 1/8" thick discs and the other to hold 1/4" thick discs.

Geiger-Muller Tube


Thin mica window detects alpha, beta, and gamma radiation. Operating range is 450-600 volts, the recommended voltage is 500 volts. Recommended anode resistor: 10 megaohms. Gas filling.
Neon and halogen. Measures .36" (9.1 mm) wide, 1.6" (40 mm) long.
Detects alpha radiation through the thin mica front window.

Sensitivity
- Alpha above 3.0 MeV
- Beta above 50 KeV
- Gamma above 7 KeV
The geiger tube comes with a black boot to protect the thin mica end window. This boot needs to be removed to detect alpha particles. However, gamma and beta particles will pass through the boot and be detected.
The United States has declared that this product for restricted exporting to foreign countries. It may still be possible, but will require additional information prior to shipping.

Analog Radiation Meter

The Analog Digital radiation meter counts the pulse output of a standard analog Geiger counter. It provides a visual readout of the CPS, approximate radiation level (imperial/metric) and analog radiation field strength meter.
- 8-12VDC or 5VDC power supply input
- Counts TTL pulses from Analog Geiger Counter
- Outputs Digital Counts Per Second (CPS) value
- Outputs radiation level (imperial / metric)
- LCD Backlight
- Available as a kit or assembled
The Analog Digital meter alternates the first line of its display between Counts Per Second (CPS) and then approximate radiation level in either imperial measurements (mR/hr) or metric measurements (mSv/hr). The top line of the display alternates its display every second. The 2nd LCD line is a analog radiation field strength meter that provides a quick visual indication of the current CPS reading.
To fit nicely on the 8 character display line the imperial measurement of mR/hr is abbreviated to mR. Likewise the meteric measurement of mSv/hr is abbreviated to mS.
The second line of the 8x2 LCD is a dedicated analog power meter to read a reasonable approximation of CPS from 1 CPS to 2040 CPS.
