Product structure composition and Principle:

Win-q3 radon detector is mainly composed of sampling, detection and signal processing. The sampling part is divided into active sampling and passive sampling. The detector mainly includes scintillation chamber, pulse ionization chamber, semiconductor and electret, etc. Signal processing means to obtain radon volumetric activity by analyzing pulse count, pulse amplitude and etching track number. Radon detector is an instrument for measuring the volume activity of radon, which is mainly used in radiation environment monitoring, radiation protection and other fields.
