Nuclear Radiation DetectorGC-01 Geiger Counter Nuclear Radiation Detector, built-in GM sensor, fast response time, high accuracy, can detect , and X-ray cumulative dose equivalent: 0.00uSv-500.0 mSv. Energy range: 48KeV-1.5MeV 30% (for 137Cs)<br><br> Intelligent AlarmEnter the alarm setting option to set the current dose alarm value and the cumulative dose alarm value. Whether the detector screen is in standby or working mode, if the detected radiation dose exceeds the alarm threshold, the radiation monitor will automatically alarm. 3 combination alarm modes of light/vibration/sound for you to choose. Multi-function Geiger CounterOur Geiger counter has other different settings, such as alarm setting, system clock setting and unit setting, and language change, you can operate in English (default) or Chinese. Easy to operate with one hand. Working PrincipleGC-01 adopts Geiger Mueller counter. A meter used to measure the intensity of ionizing radiation ( particles, rays and X-rays). Use a gas tube or chamber as a probe. When the voltage applied to the probe reaches a certain range, each time the ray is ionized in the tube, an ion pair is generated, which can be amplified to generate an electrical pulse of the same size. And it is recorded by the connected electronic equipment. The number of rays per unit time is measured. [Application] Widely used in environments with ionizing radiation. Such as home decoration radiation, geological survey, iron ore, detection vehicles, nuclear power plants, industry, radiology, radiation laboratories, etc.
