Stanford Research Institute conducted this study to provide information to assist the Atomic Energy Commission in preparing a research and development program leading to the commercial application of radiation pasteurization for selected fruits and vegetables. Under the Quartermaster Corps' extensive program of research on irradiated foods, the five fruits and vegetables (strawberries, peaches, citrus fruits, grapes and tomatoes) of interest to the AEC have been irradiated experimentally.
