目的 了解适宜于测量稳定天然辐射场的剂量率仪在脉冲辐射场中适用性问题及研究脉冲辐射场测量方法。方法 由剂量率仪测量原理推断其在脉冲辐射场中存在的问题,并实验给出了常用类型探测器在脉冲场中的测量结果,对推断进行了证明。结果 适宜于测量稳定天然辐射场的剂量率仪进行脉冲瞬变场的剂量率测量时,测量数据往往偏低。结论 实际监测过程中,应考虑以剂量监测为主,并提出有必要研发一台针对脉冲辐射场剂量率测量的仪器,以保证所得数据的合理性与可靠性。

Discussion on Monitoring of Pulsed X-ray Radiation Field

Objective To understand the applicability in pulse radiation field of the instrument which is used for measuring stability of natural radiation field and study of pulse radiation field measurement method. Methods To deduce the problems in the pulse radiation field of a dose rate meter by its measurement principle, the measurement results of the common type detector in the pulse field are given. Results When the instrument which is used for measuring stability of natural radiation field measures pulse transient field, the measurement data are usually low. Conclusion The actual monitoring must be base on strengthening the dose monitoring. It is necessary to develop a device to measure the dose rate of the pulse radiation field in order to guarantee the rationality and reliability of the data.
