GCA-01 Analog Geiger Counter


   Detects: Alpha, Beta, X-rays and Gamma Radiation
GCK-02A GCK-01A
GCA-01 Ports

Description

The GCA-01 Analog Geiger Counters are useful for detecting radioactivity and performing nuclear experiments. These Geiger Counters primary indicators are an audio click and an LED blink each time a radioactive particle is detected. The Model GCA-01 has an internal Geiger-Mueller tube. The model GCA-01W has an external wand that houses a Geiger-Mueller tube (GMT-01) and provides a easy to use probe for checking radioactivity.

  • LND 712 Geiger-Muller Tube: .38" effective diameter with a 1.5-2.0 mg/cm2 mica end window. Resolution is 0.05 mR/hr.
  • Case Dimensions app. 3.5" x 5.75" x 1.25"

Geiger Counter Technical Data


Countable Pulse Resolution & Range 1 Count Per Minute (CPM) - 5000 Counts Per Second (CPS)

Radiation Resolution: (Imperial).05 mR/hr
Radiation Range: (Imperial) Background Radiation* 18-22 uR/hr - 1000 mR/hr
Radiation Resolution: (Metric).0005 mSv/hr
Radiation Range: (Metric) Background Radiation* 0.18-0.22 uSv/hr - 10.0 mSv/hr

*Background Radiation in our location on average varies between 18-22 uR/hr Imperial (0.18-0.22 uSv/hr Metric). Your background radiation may be different due to your location and elevation on the planet. 

The GCA-01 is sensitive enough to detect background radiation as well as NORM (Naturally Ocurring Radioactive Materials) and TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials) objects in your enviroment.

GCA-01C Analog Geiger Counters


   Detects Beta, X-ray and Gamma Radiation
GCA-01C GCA-01CW
GCA-01 Ports

Description

The GCA-01C Geiger Counter is a general purpose radiation detecting instrument. It's primary radiation indicators are an audio click and an LED blink each time a radioactive particle is detected. Detects: beta, x-rays and gamma radiation. A 3.5mm Digital Output port on the side provides a TTL logic pulse each time a radioactive particle is detected. This TTL output may be used to connected to various digital adapters: The Model GCA-01 has an internal Geiger-Mueller tube.
