Abstract: Quality of captured pictures and change of dark output characteristic for the color CMOS image sensors with dif. ferent neutron doses are studied for the first time.After neutron radiation，a lot of spots and stripes Oil dark output images， and white spots as well as bunches of white spots on captured pictures appear，respectively.Quality of captured pictures ear not be obviously improved after annealing at room temperature for a long time.This is very different from those by T-ray ra. diation.The mechanism of radiation damage for CMOS image sensors is discussed.

Key words: color CMOS image sensors, neutron radiation, T-ray radiationt output characteristic：radiation damage, 输出特性, 辐照损伤
