中文摘要	Irradiation effects of proton and gamma-ray on a CVD diamond detector were studied on Beijing Tandem accelerator and /sup 60/Co source. The decrease of the detector's signal current was less than 3.5% after irradiated by 1013 cm/sup -2/,9 MeV continuous protons. Dark current didn't change obviously after the proton irradiation. The calculated radiation damage coefficient is 1. 3 * 10/sup 16/ mu m ldr cm/sup 2/, which is much higher than that of Si PIN detectors. The signal current increased a little after irradiated by 10. 32 C/kg and 1. 25 MeV gamma -ray, as the electrons excited by gamma -ray can deduce traps in diamond. And the increase is less than 0. 7%. Diamond detector has high radiation hardness and can be used in high radiation detection.
