Abstract
A polycarbonate resin composition includes: a polycarbonate resin; a polyalkylene glycol compound; and an organic-inorganic hybrid pigment, and has a yellow index (YI) of about −2 to about 4 after irradiation with gamma rays, as measured in accordance with ASTM D1925 after irradiating an about 3 mm thick specimen with gamma rays at about 25 kGy and leaving the specimen for 7 days. The polycarbonate resin composition can exhibit excellent properties in terms of color and impact resistance after being irradiated with ionizing radiation.
