EFFECTS OF NUCLEAR RADIATION ON ORGANIC FLUIDS. PART I. GAMMA RADIATION STABILITY OF CERTAIN MINERAL OILS AND DIESTER FLUIDS. Period Covered: January 1956 to March 1957
A study was made of the stability to gamma radiation of certain refined petroleum oils and diester fluids, Testing of the irradiated fluids by means of lubricant evaluation procedures, such as viscosity, flash point, and oridation- corrosion resistance, indicated that for the tests conducted, the mineral oils of the type studied should have general resistance to gamma radiation up to a dosage of about 1 x 10/sup 8/ roentgens. The diaster fluid di2-ethylhexyl sebacate (Plexol 201) had very poor stability to gamma radiation over the same range. Addition of 0.5% phenothiazine improved the radiation resistant of this base fluid, except for the loss of oxidative stability experienced at dosnge levels of 1 x 10/sup 7/ roentgens and lower. Examination was made of the test data for the irradiated fluids to detsrmine if any property changes followed the radiation exposure history. This was to discover if either the mineral oil or diaster type fluids could be used as secondary reference standards for radiation calibration of non-uniform geometries exposed to nuclear radiation, such as bearing assemblies or circulating fluid loops. The changes offering the most promise were the increase in neutralization number of the diaster fluid and the gas evolution of the mineral oils. (auth)
