A thin film of α, β-ditritiated lauric acid CH<SUB>3</SUB>(CH<SUB>2</SUB>)<SUB>8</SUB>(CHT)<SUB>2</SUB>COOH deposited from benzene on a stainless steel dish and put in a 2π gas-flow windowless counter gave a counting rate which decreased far more rapidly than was expected from the natural decay of the β-activity of tritium. We observed a distinct break point in the decay curve ten days after the deposition of the film, independent of the amount of sample taken, provided that the film was sufficiently thin.<BR>Various factors, such as impurities, surface migration, exchange reaction and evaporation, were considered to explain the phenomena; among these the evaporation of the lauric acid from the deposited surface film of the composite structure was proved to be the main factor responsible for these phenomena.
