A method is described for calibrating a Remote Working Level Monitor, an instrument which measures Working Level and Rn-daughter concentrations in the atmosphere. The method makes use of a microprocessor to calculate beta efficiencies for RaB and RaC from the counts accumulated in the RaA, Ra(B + C) and RaC' channels of the instrument. Both the alpha spectroscopic and total-alpha methods are used to determine the Rn-daughter concentrations. These methods require the processor to solve systems of linear equations with several unknowns. No assumptions about Rn-daughter equilibrium are made.
