Based on Geiger-Miller counting principle, the natural radioactivity of radon attached to particulate matter in the air is measured by β-ray counting, and the atmospheric diffusion degree near the ground is obtained according to the measured value, thus the atmospheric stability is obtained. Combined with meteorological factors, pollutants in the air such as smog, PM2.5, ozone and VOC can be comprehensively analyzed.
It is suitable for government environmental monitoring departments, super monitoring stations, industrial park monitoring stations, scientific research institutes, universities and so on.
