Data-acquisition systems for radon monitoring
Abstract
A data acquisition system with five continuous flow monitors was designed for monitoring radon in the field and laboratory. The system can be set to monitor each detector up to 16.5 minutes and has a lower limit of 50 Ci/l and no upper limit. All five detectors are accurate to plus or minus 15 percent of the total alpha count. The continuous flow monitor was calibrated in the laboratory at four different radon concentrations, and a least square fit was determined so that the total alpha count could be converted into p Ci/l of air. It was then checked against the two filter method at three concentrations with good agreement.
