摘　　要：介绍了脉冲X射线在ST401塑料闪烁体上的相对灵敏度标定方法,并在"晨光号"脉冲X射线源和钴辐照源上,实验标定了厚度从1～50mm的六种规格塑料闪烁体的相对灵敏度,并给出了标定数据的不确定度评定,其标定数据能够作为ST401塑料闪烁体相对灵敏度转换的实验依据。The relative sensitivity calibration method of the pulsed X - ray in ST401 plastic scintillator is presented. Experimental relative sensitivity calibrations of the plastic scintillators of different thicknesses from 1 mm to 50 mm are accomplished on the ＂Chenguang＂ pulsed X -ray source and a Co radioactive source, The uncertainty of the calibration data is evaluated, which can be treated as the experimental evidence for the relative sensitivity conversion of ST401 plastic scintillator.
