Alpha / beta low background probe
The probe is composed of a diameter 45mm low background alpha / beta scintillator and a low noise photomultiplier tube, which can be used in conjunction with a portable scaler. It is easy to use, stable in performance and cheap in price. This instrument can be used for environmental protection monitoring, sanitation and epidemic prevention, radioactive laboratories, hospitals, scientific research units and other departments.
Main technical indexes of alpha probe：
Diameter of sample plate: [Phi] 50mmEfficiency: ETA P (239Pu) > 80%/2 pi
Background: < < 0.002cm-2min-1
Efficiency stability: the instrument is continuously electrified for 8 hours, and the detector efficiency varies by 3%.
Main technical indexes of beta probe：
