Mortality and shock-avoidance performance were observed in Wistar albino rats subjected to pulsed ionizing radiation from two different nuclear reactors. In one, the ngamma dose ratio obtained ranged from 2.51 to 6.61, and the pulse width was 48 microsec. at half-amplitude. In the other, the pulse half-width was either 10 to 150 msec., and the ngamma tissue dose ratio used ranged from 123 to approximately 5.31. Author
