Standard aircraft hoses and couplings contain organic polymeric materials which are affected significantly by nuclear radiation. To determine the functional life of these items when exposed to radiation, tests were conducted at controlled conditions of temperature, pressure, type of internal fluid, and radiation-exposure rate. Buna N, a solvent-resistant synthetic rubber, and Teflon, a temperature-resistant plastic, were the hose materials for most of the tests. These hoses were irradiated by gamma rays at conditions simulating actual operation for a specified time or until leakage occurred. Buna N hose withstood exposure dosages up to 4 x 10/sup 8/ ergs g/sup -1/(C) before leaking, compared with 1 x 10/sup 8/ ergs g/sup -1/(C) for Teflon hose, both at static pressures of 1200 psig and temperatures up to 350 F. The exposure dose required for failure of Teflon hose by intermittent pressure (0 to 1000 psig) was about 1 x 10/sup 7/ ergs g/sup -1/(C) at 350 F. (auth)
