The Repair of Potentially Lethal and Sublethal Damage in Unfed Plateau-Phase Cultures Irradiated at 0.78 Gy/hr

Abstract
Unfed plateau-phase cultures of Chinese hamster ovary (CHO) cells were irradiated at 0.78 Gy[gray]/h to determine if accumulation and repair of sublethal and/or potentially lethal damage diminished as a function of small multiple doses and whether culture age affected repair. The repair of both potentially lethal and sublethal lesions was unaffected by aging or absorbed dose.
