THE ACUTE MORTALITY RESPONSE OF BEAGLES TO MIXED GAMMA-NEUTRON RADIATIONS AND 250 KVP X RAYS

Abstract

Beagle median lethality studies were conducted using 250 kVp x rays and TRIGA reactor (mixed gamma-neutron) radiations. Purebred beagles were irradiated at midline tissue doses from 166 to 292 rads. The dose rates were approximately 17 rads/min, and exposures were Class A uniform. LD50/60 values of 206 plus or minus 3.6 and 218 plus or minus 3.0 rads were obtained for the x rays and the mixed gamma-neutron radiations, respectively. The RBE of the mixed gamma-neutron radiations was 0.94. Hematological values, clinical symptoms, and survival time data were also collected.
