Abstract
The overall efficiencies of two radon progeny monitors were evaluated by both theoretical and experimental methods. Three factors were considered in the theory: plateout loss in the inlet channel, filter and alpha counting efficiency. One of the monitors had a long rectangular inlet channel, while the other had a short cylindrical inlet. Two particle sizes, 1 nm and 100 nm in diameter, were considered since both are important in practice. From the experiments, the overall efficiencies for the rectangular inlet monitor were found to be 0.7% for 1 nm particles and 37.3% for 100 nm particles. The corresponding values for the cylindrical inlet monitor were 8.7% and 12.9%. There was generally good agreement between theory and experiment.
