摘　　要：文章介绍辐射权重因子的概念和发展变化，分析中子辐射权重因子与剂量监测之间的关系。根据中子能量给出了相应的辐射权重因子的数值。根据所得的中子辐射权重因子对中子剂量测量的影响规律得出，在设计中子剂量当量测量仪器时，需充分考虑到品质因数和辐射权重因子数据的变化，并应按照新的辐射权重因子数据进行刻度。The paper introduces the concept and development of radiation weighting factor, and analyzes the relationship between neutron radiation weighting factor and dose monitoring. Based on the neutron energy, the value of weighting factor was given. For designing the neutron dose equivalent instrument, the variations of quality factor and radiation weighting factor must be considered, and the calibration of instrument according to new radiation weighting factor is necessary.
