摘要

<正>Hypersensitive response of mammalian cells in cell killing to X andγrays has been reported at doses below 1 Gy. The purpose of this study was to examine the low-dose sensitivity of human hepatoma SMMC-7721 cells irradiated with 60Coγrays and 50 MeV/u 12C ions. Experiments-of usingγrays and charged particle irradiation were performed, particularly in the low-dose range from 0 to 2 Gy. The survival effect
