The effect of a single irradiation of X-rays on the thymus of young rats was studied. The thymic involution and recovery has been investigated by checking weight, morphology and histology. An early and severe histological damage was observed as well as the occurence of a mitotic block within the first hours following irradiation. The mitotic acticity is re-established shortly after.
