Changes in surface architecture and three dimensional structure of rat thymus cortex were examined by scanning electron microscopy (SEM) after a whole-body X-irradiation. The samples of thymus prepared from rats 4 to 8 hr after a 400 R irradiation were observed by SEM. Normal thymocytes, having tiny microvilli and shallow ridges, decreased in number after irradiation, with a corresponding increase in radiation damaged round shaped cells with occasional protrusions and pores. With time after irradiation, smaller spherical fragments of cells having smooth or porous surfaces increased in number.
