GC-01 Geiger Counter Nuclear Radiation Detector & Dosimeter

Q: What types of radiation can the GC-01 Geiger Counter detect?

The GC-01 Geiger Counter is designed to detect gamma (γ) rays, X-rays, and hard beta (β) rays using its professional-grade GM energy compensation tube. It covers an energy range of 48 keV to 1.5 MeV, making it suitable for a wide variety of radiation detection scenarios including home building materials, medical equipment environments, and industrial monitoring.

Q: Can I use the GC-01 to test marble, granite, or ceramic tiles for radiation?

Yes! The GC-01 is specifically suited for testing natural stone building materials such as marble, granite, and ceramic tiles, which can sometimes contain naturally occurring radioactive materials (NORM). Simply hold the device near the surface, and the color display will show real-time radiation levels in seconds.

Q: How long does the battery last on a single charge?

The GC-01 features a built-in 1,100 mAh lithium-ion battery rechargeable via a standard Type-C cable. Battery life varies depending on screen brightness and alarm usage, but the high-capacity battery is designed for extended all-day use — ideal for field work, outdoor exploration, or long indoor monitoring sessions.

Q: How does the alarm system work?

The GC-01 offers a triple alarm system consisting of an audible beep, a flashing LED light, and vibration. When radiation levels exceed your preset safe threshold, all three modes activate simultaneously to ensure you receive an immediate alert — even in noisy environments or when the device is in your pocket.

Q: What measurement units does the GC-01 support?

The GC-01 supports five interchangeable units of measurement: µSv/h (microsieverts per hour), µGy/h (microgray per hour), mR/h (milliroentgen per hour), CPS (counts per second), and CPM (counts per minute). You can switch between units at any time using the intuitive control buttons on the device.
