The RAD-S40 is a diffusive radon measurement sensor designed for static air diffusion measurement of radon gas concentration in the environment. It uses the radioactive characteristics of radon gas and its daughters, obtaining alpha counts through a planar silicon detector and signal acquisition system, then calculates radon concentration to achieve long-term continuous monitoring of radon levels.
