This is a handheld Geiger counter built around an energy-compensated GM tube. It reads beta, gamma and X-ray radiation in real time, with average and accumulated dose modes, and a 0.01 µSv/h resolution. It suits preppers, travelers, scrap and salvage buyers, and anyone checking a home, basement or secondhand item for contamination. Against basic GM counters it adds energy compensation and rechargeable power; against lab-grade survey meters it is a consumer tool with a narrow dose range and no alpha detection.

The Portable Digital Radiation Detector measures beta, gamma and X-ray radiation. It shows readings in real time, so you can check radiation levels in your surroundings as you move around. It can be used for personal safety, environmental assessment or professional work.
It uses an energy-compensated GM tube, which responds across an energy range of 48keV to 1.5MeV. The display shows real-time, average and accumulated values. The detector is compact and runs on a rechargeable lithium polymer battery.
