Features 1. Nuclear Radiation Detector: It uses a Geiger Miller counter, which detects ionizing radiation（ β Particles, γ A counter for the intensity of radiation and X-rays. Accumulated dose equivalent: 0.00uSv-5.00mSv. Energy range: 48KeV-1.5MeV ≤ ± 30% (for 137Cs γ） 2. Intelligent Alarm: Enter the alarm setting option and set the current dose alarm value and cumulative dose alarm value. Whether the detector screen is in a sleep or working state, if the detected radiation dose exceeds the alarm threshold, the radiation monitor will automatically alarm. Three combined alarm modes of light, vibration, and sound are available for selection. 3. Multifunctional Geiger Counter: Our Geiger counter also has various other settings, such as alarm settings, system clock settings, unit settings, and language changes, making it easy to operate with one hand. 4. Working Principle: Counter is used to detect ionizing radiation（ β The intensity of particles, gamma rays, and x-rays. Use a gas tube or small chamber as the probe. When the voltage applied to the probe reaches a certain range. Each time a ray ionizes in a tube, it produces a pair of ions that can be amplified to produce an electrical pulse of the same size. And recorded by the connected electronic device. From this, the number of rays per unit of time is measured. 5. Application Field: Widely used in environments with ionizing radiation. Such as home installed radiation, geological survey, iron, testing vehicles, nuclear power plants, industry, radiology, radiology laboratories, etc. Specification Material: ABS Color: Yellow, Blue Size: 12 X 8 X 3 cm Weight: 250 g Package Include: 1x Nuclear Radiation Detector
