title: T-lymphocyte levels in the peripheral blood of gamma irradiated rhesus monkeys.
abstract: Circulating Thymus derived (T) lymphocytes were studied in Rhesus monkeys exposed to single whole body gamma radiation with doses of 400, 500 and 600 Rad. Spontaneous lymphocyte rosette assay (E-rosettes) was used to evaluate the level of T-lymphocytes. A decrease in total leukocytes, lymphocytes and T-lymphocytes levels was observed beginning from the 5th day after irradiation and continued for several weeks after radiation.
