Nuclear Radiation DetectorFNIRSI GC-01 Geiger counter nuclear radiation detector, built-in GM sensor, fast response time, high precision, capable of detecting Gamma, Beta and X-rays. Cumulative dose equivalent: 0.00uSv-500.0mSv. Energy range: 48KeV-1.5MeV 30% (for 137Cs) [Intelligent alarm] Enter the alarm setting option, set the current dose alarm value and the accumulated dose alarm value. No matter the detector screen is in sleep state or working state, when the detected radiation dose exceeds the alarm threshold, the radiation monitor will automatically alarm. 3 combined alarm modes of light/vibration/sound are available. Multifunctional Geiger CounterOur geiger counter also has various other settings, such as alarm clock setting, system clock setting and unit setting and language change, you can operate in English (default) or Chinese. Easy one-handed operation. Working principleFNIRSI GC-01 adopts Geiger-Miller counter. Counters are used to detect the intensity of ionizing radiation (beta particles, gamma rays, and X-rays). Use the trachea or chamber as the probe. When the voltage is applied to the probe the current reaches a certain range. Whenever the ray ionizes in the tube to produce a pair of ions, it can be amplified to produce an electrical pulse of the same size. and recorded by connected electronic devices. The rays per unit of time thus measured. Application FieldsWidely applicable to environments with ionizing radiation. Such as home improvement radiation, geological survey, iron ore, inspection vehicle, nuclear power plant, industry, radiology department, radiation laboratory, etc.
