Based on uncertainty analysis of the α spectroscopy program for measuring the 222Rn/220Rn daughters
the relationships among the sampling time
measurement intervals
and total measurement time and measurement uncertainty are studied in details
and an optimal measurement program was given for quick and accuracy determination of the 222Rn/220Rn daughter concentrations in air. The optimal program was also proved by comparing the results with several measurement programs by other researchers in theory and practice.
