摘　　要：介绍了不同结构比例的PIN宽基硅二极管快中子剂量探测器对239Pu-Be中子源的剂量响应测试结果。通过对实验结果进行分析,建立了探测器的等效电路模型,得出了探测器的剂量响应与结构比例参数(d/A)近似成线性关系的结论。The wide-base silicon diode for fast neutron dose monitoring is studied, and the dose response of the diodes with different structural ratio to ^(239)Pu-Be neutron source was given. Based on the results, equivalent model of circuit was built, and the conclusion was drawn that the neutron dose response varied linearly with the parameter of the structural ratio of the detector.
