FNIRSI GC-01 Geiger Counter Nuclear Radiation Detector, Radiation Dosimeter with LCD Display, Portable Handheld Beta Gamma X-ray Rechargeable Radiation Monitor Meter, 5 Dosage Units, 0.0Sv-500mSv

Nuclear Radiation DetectorFNIRSI GC-01 Geiger counter nuclear radiation detector with built-in GM sensor, able to detect Gamma, Beta and X-rays.
Cumulative dose equivalent: 0.00 uSv- 500.0 mSv.
Energy range: 48 KeV- 1.5 MeV plus/minus 30%for 137 Cs). Smart Alarm3 modes of Light/Vibration/Sound. Geiger counter can set current dose alarm value and cumulative dose alarm value. Whether in sleep or active state, the radiation monitor will alarm if the detected radiation dose exceeds the alarm threshold. Multifunctional Geiger CounterOur the geiger counter has other various setting, such as alarm setting, system clock setting and unit setting & language change, you can operate in English (default) or Chinese. Easy one-handed operation. Working PrincipleFNIRSI GC-01 radiation meter uses a trachea or small room as a probe to detect ionizing radiation gamma/Beta/X-ray. Radiation ionization generates ion pairs, ions are enlarged and converted into electrical pulse counts to measure. Application AreasWidely applied in the environment where existing ionize radiation. Such as home improvement radiation, geological survey, iron, Inspection vehicles, nuclear power plants, industry, radiology, radiology laboratories and so on
