Abstract : Iodine, bromine, and chlorine have been determined by means of neutron activation analysis in a series of aerosols and rain-water samples collected in Hawaii. Five-milliliter samples of rain water are used in the analytical procedure, and no chemical treatment is required before pile irradiation. Freedom from errors due to contamination and species-specific chemical steps is thus assured. The ratio I/Cl in the aerosols and rain water is more than 100 times greater than published values for sea water, but the ratio Br/Cl is the same as that for sea water within a factor of 2. The seven samples of rain water, collected in October and November 1961, and the eight samples of aerosols, collected from a light aircraft in May 1962, show (1) that I/Cl is greater in rain by a factor of 3, (2) that Br/Cl is greater in rain by a factor of 2, and (3) that I/Br is greater in rain by a factor of 1.5.
