LONG-TERM RAT FEEDING EXPERIMENT ON IRRADIATED BEEF. Progress Report No. 3-C for period September 3, 1958 to March 31, 1959

Ground beef irradiated at zero, 2.79, and 5.58 megarads was fed to three replicates of 54 rats each. Weight gains were uniform on the three levels of diet. Hematologic values remained normal, and no hemorrhagic disease was observed. Eight male and three female rats expired due to respiratory disease or tumors. No effects related to the toxicity of the irradiated beef were noted. (auth)
