This Nuclear Detector Dosimeter is designed specifically for measuring β, γ, and X-ray radiation. It excels at detecting even the slightest variations in radiation levels and exhibits exceptional sensitivity towards the most commonly encountered nuclides. The detection mechanism relies on a Geiger-Müller (GM) counter tube, which registers ionizations produced by each ray passing through it. Consequently, the GM tube generates detection current pulses, and these pulses are captured by the electronic circuitry of the device and recorded as counts. In the selected mode, the displayed value on the dosimeter corresponds to the count value.
