Crosslinking, or polymerization, and cleavage are the chief radiation effects on organic compounds. In a study of lubricants, the stability of the base oil was the most important as pect of radiation resistance. Polyphenyl ethers and alkyl aromatics were the chief lubricants studied. The success of the organic cooland used in OMRE encouraged further research into the nature of radiolysis products as a basis for applying advanced chemical and physical separation shcemes to degraded coolants. Crosslinking increased the tensile strength, hardness, and elastic modulus of plastic, while cleavage had the opposite effect. The major effects observed after irradiation of polyethylene were hydrogen evolution, crosslinkage, increased unsaturation, destruction of crystallinity, and color changes. Mehtacrylate polymers were found to cleave on irradiation. The most significant development in the study of radiation effects on elastomers was the use of additives (antirads) to produce radiation-resistant rubbers. Rubbers vulcanized by irradiation were studied because of their high resistance to aging. (M.C.G.)
