A thermoplastic composition comprises a polycarbonate, an ionizing radiation stabilizing additive, and a poly-substituted aromatic compound of formula:
wherein X is an aryl group; Y is a non-hydrogen substituent group, a is 1 to 4, b is 0 to 4, a+b is less than or equal to 4, and c is 0 or 1; and wherein the amounts and identities of the polycarbonate, ionizing radiation stabilizing additive, and poly-substituted aromatic compound are selected such that a molded article having a thickness of 3.18 millimeters and comprising the thermoplastic composition has, after exposure to gamma radiation at 83 kGy and when measured according to ASTM D1925-70, an increase in yellowness index (dYI) of less than or equal to 50, when compared to the unexposed thermoplastic composition.
