Application
The Alpha-Beta-particulates monitor LB 150 D-R can be deployed for the measurement of airborne artificial Alpha and Beta activity in
The Particulates Monitor LB 150 D-R uses a fixed filter and is a true real time Monitor while collection, detection and evaluation are done simultaneously.
Sampling
The very high sampling rate of 40 m³/h ensures a representative sampling for both Stack monitoring with Isokinetic extraction as well as Room or workplace air monitoring.
Particulates collection and Detector
The sampled air is drawn through an S-class glass fiber filter with 200 mm Ø. The detector, a large surface proportional counter with thin entrance window, is located directly above the collection area at a distance of 7 mm and measures the radiation intensity from Alpha and Beta decays.
The airtight particulates collection unit can be constructed in Stainless steel or in Teflon depending on the application.
