脉冲辐射探测技术是探知核反应过程特征信息的重要途径之一,是核反应过程特征性研究、核装置设计、运行、监测与控制不可缺少的技术手段。随着核科学技术的发展,强流瞬态脉冲辐射场的产生、应用成为新的研究热点。强流瞬态脉冲辐射场的剂量测量变得越来越重要,脉冲射线束测量技术的特点之一是它所测量的核辐射是以脉冲形式出现,探测器输出信号是大量粒子作用结果所形成的一个脉冲信号。第二个特点是单次脉冲的测量,测量对象不重复出现。但是,高剂量率的监测十分困难,测量γ射线剂量
Pulsed radiation detection technology is one of the important ways to detect the characteristic information of the nuclear reaction process. It is an indispensable technical measure for the characteristic research of nuclear reaction process, the design, operation, monitoring and control of nuclear devices. With the development of nuclear science and technology, the generation of strong current transient pulse radiation field has become a new research hotspot. It is more and more important to measure the dose of transient pulsed radiation field of strong current. One of the characteristics of pulsed beam measurement technology is that the nuclear radiation measured by it is in the form of pulse. The detector output signal is formed by the result of a large number of particles A pulse signal. The second feature is the measurement of a single pulse, the measurement object does not appear repeatedly. However, the monitoring of high dose rates is very difficult, measuring gamma doses
