Abstract : Rats exposed to x radiation 24 hours prior to antigen administration exhibited detectable skin reactions to tuberculin 2 days later than nonirradiated sensitized controls. Reaction sizes illustrate that the irradiated rat experienced a decreased sensitivity to tuberculin which persisted through day 14. The radiation dose (475 rads) responsible for the observed depression of the delayed skin reactions produced a greater depression of the circulating antibody response. The results obtained suggest that the cellular and humoral immune responses in the rat are radiosensitive.
