/sup 210/Pb, /sup 210/Bi and /sup 210/Po were measured in 17 rain samples collected at Fayetteville, Arkansas, during April through June 1973, and /sup 210/Pb and /sup 210/Po were measured in 108 additional rain samples collected during September 1973 through April 1975. In 12 out of 17 samples, the residence time calculated from the /sup 210/Bi//sup 210/Pb and /sup 210/Po//sup 210/Pb ratios were either concordant or near concordant. The discordant residence times in the other samples result from the mixing of two different air masses: one represented by a short and the other by a much longer residence time of the radon daughters. /sup 210/Pb and /sup 210/Po were sequentially sampled from three rainstorms which occurred on October 6, 1973 and February 18 and April 18, 1974. In the case of the October 6, 1973 rain the /sup 210/Po//sup 210/Pb ratio was found to vary markedly within a single rainfall, indicating that a mixing of two air masses occurred during the rainstorm with one air mass represented by a residence time of about 30 days and the other roughly 300 days.
