title: An algorithm for source checking continuous air monitors using radon progeny.
abstract: Department of Energy requirements contained within 10CFR835 require that continuous air monitors be periodically checked for operability. The DOE air monitoring implementation guide for 10CFR835 allows the use of radon progeny to perform the recommended weekly source check. The Defense Waste Processing Facility located at the Savannah River Site has demonstrated that, through the use of the Hypotheses Concerning Two Means, diurnal change in the radon progeny detected by the monitors meets the requirements for weekly source checks. The use of the diurnal change in radon progeny has replaced the person-hours expended performing direct weekly source checking with an automated system requiring minimal person-hour expenditure.
