Product Introduction

The mobile radioactive aerosol detector is designed to monitor environmental contamination levels of radioactive aerosols, providing a basis for personnel protection. The detector is mainly composed ofa sampling unit, a detector unit, a data communication unit, and a display unit. The detector unit employs ion-implanted silicon detectors, located within the sampling pipeline, just above the filter paper. The use of fluorine material micro-porous filter membranes reduces the radon progeny drag. The instrument performs automatic energy calibration, efficiency calibration, and spectrum analysis. It uses advanced energy spectrum fitting subtraction methods to eliminate radon progeny interference, providing net counts for the desired artificial alpha and beta nuclides. It calculates their concentration and detection limits. The detector can display radioactive volume concentration in user-defined units and emits audio-visual alarms when measurements exceed the threshold.
