Abstract
Concentrations Of 222Rn, 210Pb, 210Bi, 210Po, and 90Sr were determined in surface air on the windward side of Hawaii. About three fourths of the 222Rn on the lower slopes of the island is due to emanation from the island surface, whereas the remainder of the 222Rn and most of its long-lived radioactive daughters, 210Pb, 210Bi, and 210Po, are advected from distant continental sources. The transient time of air masses over the island, the transit time from distant continental regions, and the mean aerosol residence times above and below the trade wind inversion are estimated to be about 13 hours, 15–20 days, and 5 and 2 days, respectively.
