ALPHA RAY DETECTOR WITH AN OPTICAL SENSOR FOR MEASURING RADON CONCENTRATION IN AMBIENT AIR

摘要

The invention relates to an alpha radiation detector (1) for measuring the radon concentration in the ambient air, comprising a housing (10) with a chamber (9) located therein, the housing (10) being designed in such a way that ambient air enters the chamber from the outside (9) can penetrate, and an optical sensor (4), characterized in that an inner wall of the housing (10) is provided with a scintillation material (3) which, when alpha particles (7) strike it, generates light pulses (8) which from the optical sensor (4) can be detected.
