Abstract

Problems which the solid propellant rocket engineer will encounter in designing for long-term storage in a radiation environment are discussed. A summary of present knowledge of the radiation environment is given. Mechanisms of radiation degradation and its effects on tensile properties of propellant binders are discussed qualitatively. Data from a program of irradiation of several propellants is presented. Properties of two of the propellants were changed significantly by doses of the order of 4 x 10(exp 6) rads.

Abstract

SummaryRepeated intravenous injections of homologous erythrocytes, begun in the early neonatal period, later resulted in the inability of the recipients to destroy rapidly the same homologous erythrocytes. This behavior contrasted with that of control chickens from the same hatching, which uniformly and rapidly destroyed the same donor blood.
