EARLY EFFECTS OF 150-MEV PROTON IRRADIATION IN RHESUS MONKEYS
Abstract
Rhesus monkeys were exposed to 150-Mev proton irradiation at 11 rads per minute. After exposure, the animals were observed for clinical changes and mortality. Hematologic studies were performed up to 80 days after exposure. On the basis of acute median lethal dose, mean survival time, clinical observations, and blood cell depression, an RBE of unity was assigned when comparing the 150-Mev proton exposures with 2-Mev x-ray exposures. A decrease in median lethal dose was noted with lowered dose rate when proton exposures at 57 rads per minute and 11 rads per minute were compared.
