Abstract
Mice were subjected to pulsed exposures of either fission spectrum neutrons or gamma radiation. No significant differences in LD50/30 have been detected. In the neutron irradiation studies the comparison was made between pulsed (PP) dose rates of 0.4-1.0 x 106 rads/min and a rate of 40 rads/min achieved with sustained (SS) reactor operation (first collision doses); the LD50/30 in both groups approximated 300 rads (mid-line tissue dose). Likewise, no difference in LD50/30 was found in gamma irradiated animals exposed to PP dose rates of 0.9-40. x 106 rads/min and SS animals irradiated at 100 rads/min; in both groups the LD50/30 approximated 790 rads.Keywords
