[Effect of ionizing radiation on the aggressive behavior of mice]

Changes in the aggressiveness of mice were studied after exposure thereof to 5, 10, 30, 60 and 100 Gy radiation. With doses of 5, 10 and 30 Gy no stable effect on the aggressive behaviour of mice was observed, while doses of 60 and 100 Gy suppressed it drastically. Stress at the time of exposure can enhance the antiaggressive effect of radiation.
