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 radsmin, and exposures were Class A uniform. LD5060 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.
