Alternative concepts for design of air monitoring instruments: In-line and open face reference samplers and a new method of demonstrating alpha CAM performance

Over the past several years Los Alamos, Texas A&M University and Canberra Instruments have been collaborating on the development of advanced continuous air monitoring and air sampling concepts and technology. We have successfully completed the design of an alpha CAM which embodies a number of innovations in the way radon progeny background interference is controlled and compensated, and in the way data processing, alarm generation, and data communication are handled.
