915 Generation FNIRSI GC-01Nuclear radiation detector Home professional radioactive ray ionization personal dose alarm instrument Geiger counter

Is a special detection of ionizing radiation (X-ray, y ray, B ray) intensity of the counting instrument, by an inflated tube or chamber as a probe, when the voltage applied to the probe reaches a certain range, the ray in the tube each ionization produced a pair of ions, can be amplified to produce an electrical pulse of the same size and is recorded by a connected electronic device. So you can measure the number of rays per unit time.
