title: Measurements of the dispersal of aerosol sprays in a room and comparison to a simple decay model.
abstract: A series of tests is described that measured the concentration of aerosol ingredients in a test room for a period of several hours after spraying. The results were compared to a simple exponential decay model used by the industry to predict exposure to aerosol ingredients. The results showed that the model can be used to predict exposure once the ingredients had become dispersed throughout the room, and that the exposure dose is initially heavily influenced by location during the period soon after spraying.
