[The function of the blood reduction systems in people after contact with ionizing radiation at low doses].

An integral rate of a flow of reduction equivalents from intraerythrocytic reducing agents to an external electron acceptor (potassium ferricyanide) was measured to investigate antioxidant capacity of the erythrocytic reducing systems in persons after a contact with small doses of ionizing radiation (0.06-0.25 Cy) 12 mos. before the investigation. A potentiometric method with the help of a redoxstat was employed. Altogether 47 persons (44 men and 3 women) aged 19 to 50 (33.8 +/- 0.96) were investigated. A conclusion is that the condition of the erythrocytic reducing system in persons after a contact with small doses of ionizing radiation can be regarded as normal.
