This paper presents experimental results of dynamic breakdown voltage and delay response as functions of gamma ray air kerma rate for xenon-filled tube at 2.7 mbar pressure. Gamma ray air kerma rate range was considered from 123 nGy h^–1 up to 12.3 mGy h^–1 in order to investigate the possibility of the application of this tube in gamma radiation dosimetry. It was shown that the variations of the above-mentioned parameters are considerable up to the dose rate of 1.23 μGy h^–1, which points to the possibility for application in small dose rate gamma ray dosimetry. Physical processes that make dominant impact to dynamic breakdown voltage and delay response during xenon-filled tube irradiation are also discussed in the paper.

氙气管击穿电压和延迟响应的研究，作为可能的小伽玛射线空气比释动能速率的同质参数。

本文介绍了氙气填充管在2.7 mbar压力下的动态击穿电压和延迟响应随伽马射线空气比释动能速率变化的实验结果。伽马射线空气比释动能的速率范围从123 nGy h ^–1到12.3 mGy h ^–1，以研究该管在伽马辐射剂量测定中的应用可能性。结果表明，直至1.23μGyh ^–1的剂量率，上述参数的变化都相当大，这表明可以在小剂量率伽马射线剂量测定中应用。本文还讨论了在氙气管辐照期间对动态击穿电压和延迟响应起主要影响的物理过程。
