FNIRSI GC-01 Geiger counter Nuclear Radiation Detector Personal Dosimeter X-ray γ-ray β-ray Radioactivity Tester Marble Detector(Blue)

- The FNIRSI GC-01 nuclear radiation detector uses a higher-precision Geiger-Miller counter.
- Counter for detecting the intensity of ionizing radiation (beta particles, gamma rays and x-rays).
- Use a gas tube or a small chamber as a probe.When the voltage applied to the probe reaches a certain range.Each time the ray is ionized in the tube to produce a pair of ions, it can be amplified to produce an electric pulse of the same size.And recorded by the connected electronic device.
- The number of rays per unit time thus measured.The alarm threshold measurement rate can be arbitrarily selected.
