[Stimulating effect of long-term small-dose radiation on lymphopoiesis in mammals].

Mathematical models of lymphopoietic variations in mammals exposed to acute and chronic irradiation have been developed. They are based on the cheilone theory of hemopoiesis regulation. The models are systems of 9 nonlinear differential equations. They give a qualitative and quantitative description of lymphocytes in peripheral blood and their precursors in bone marrow of irradiated mammals. These models have for the first time simulated the stimulating effect of prolonged irradiation with small dose rates on recovery processes in the lymphopoietic system.
