Abstract
In the thymus the small lymphocytes were the most radioresistant and the large lymphocytes were repopulated before the medium-sized lymphocytes. As the radiation dose was increased from 50 to 400 r, there was a decrease in the large to small thymocyte ratio, and a longer time period was required for a return to the normal ratio. Single and repeated doses of X-irradiation produced much the same type of effect on the large to small ratio of both thymus and spleen lymphocytes, and it was concluded that the effects of X-irradiation on the cell size distribution of lymphocytes in the thymus and spleen were similar.
