The FH 62 C14 continuous ambient particulate monitor measures the mass concentration of suspended particulate matter (e.g., TSP, PM10, PM2.5, PMC and PM1) by use of beta attenuation. In addition, the ambient radioactive influence of natural Radon (Rn-222) gas is measured as a refinement step toward better sensitivity at lower ambient particulate concentrations.
The FH 62 C14 particulate sample collection area is located between both the C14 source and the proportional detector. While ambient particulate matter is being deposited onto a filter tape sample spot, the dynamic filter loading is measured continuously by the attenuation of the C14 source beta rays. As a result, a continuous real-time measurement of airborne particulate is provided.
It is not necessary to move the filter spot from the sample position to the detector position for zero and mass determination.
