本文报告了用于测量高强度脉冲中子及γ射线剂量的真空室探测器和直读真空室剂量计的研制。两种真空室在γ、Ｘ射线、１４ＭｅＶ中子、稳态和脉冲核反应堆中子、γ射线混合场上实验表明，其主要剂量学性能基本上达到设计要求。真空室剂量计在１０￣４Ｇｙ／ｓ下无剂量率依赖性，含氢材料壁真空室的快中子、γ射线灵敏度比近１：１，铝壁真空室受１０￣６Ｇｙ（￣（６０）ＣＯ）照射，其性能几乎没有变化。 This article reports the development of a vacuum chamber detector and direct reading vacuum chamber dosimeter for the measurement of high intensity pulsed neutron and gamma radiation doses. Experiments on γ, X-ray, 14MeV neutron, neutron and γ-ray mixing fields in both steady-state and pulsed nuclear reactors show that the main dosimetric properties of the two vacuum chambers basically meet the design requirements. The vacuum chamber dosimeter has no dose-rate dependency at 10 ~ 4 Gy / s, the neutron sensitivity of gamma-ray in the vacuum chamber with hydrogen-containing material is nearly 1: 1, and the vacuum chamber of aluminum wall is affected by 10 ~ 6 Gy (~ CO) irradiation, the performance of almost no change.
