摘要/Abstract

摘要： γ辐射剂量率测量是辐射环境监测工作的重要部分,宇宙射线响应值的扣除对γ辐射剂量率测量的准确性起着至关重要的作用。为解决现阶段宇宙射线响应测量中常用的带压舱石的玻璃钢船、小木船等测量载体的不足,引入浮筒平台、冰面等宇宙射线响应测量载体,开展了在不同测量载体、不同测量场景下各仪器宇宙射线响应值的测量及其影响的因素分析。结果表明,高气压电离室宇宙射线响应测量值范围为33.4～41.4 nGy/h,塑料闪烁体探测器宇宙射线响应测量值范围为8.7～12.6 nGy/h ;各仪器宇宙射线响应测量值为:玻璃钢船＞冰面≥小木船≈浮筒平台。综合来看,浮筒平台是目前最有效、便捷且经济的测量载体。

Abstract: Measurement of gamma radiation dose rate is an important part of radiation environment monitoring work, and the deduction of cosmic ray response value plays a crucial role in the accuracy of the measurement of gamma radiation dose rate. To address the limitations of the pressure-hull glass fiber boats and small wooden boats commonly used in current cosmic ray response measurement, this study introduces floating platforms and ice surfaces as measurement platforms for cosmic ray response measurement and conducts measurements of the cosmic ray response values of various instruments under different measurement platforms and scenarios. The results show that the measured cosmic ray response of high pressure ionization chamber ranges from 33.4 to 41.4 nGy/h, and that of the plastic scintillator detector ranges from 8.7 to 12.6 nGy/h. The measured cosmic ray response values of each instrument follow the following rules: glass steel ship > ice surface ≥ small wooden ship≈buoy platform. Overall, the new buoy platform is the most effective, convenient and economical measurement platform available.

Key words: cosmic ray response, gamma radiation dose rate, measurement platform, buoy platform, ice surface, frp ship
