Detects Beta, X-ray and Gamma Radiation
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.
- Detects: Beta, Gamma and X-Rays.

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-01C series 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.
