FNIRSI GC-01 Nuclear Radiation Detector

The FNIRSI GC‑01 is a compact handheld nuclear radiation detector engineered to detect and monitor ionizing radiation in real time. Using a high precision Energy Compensation Geiger Müller (GM) counter tube, the GC‑01 can measure gamma rays, X-rays, and beta rays with clear visual readouts and multiple alert modes. Its portable design, built in rechargeable battery, and intuitive interface make it suitable for quick safety checks, environmental monitoring, and general radiation awareness. 

Designed for both beginners and advanced users, the GC‑01 provides real time dose rate and cumulative dose equivalent measurements while offering adjustable units and alarm settings. It’s ideal for field use, workshop diagnostics, and everyday radiation monitoring tasks.
