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.关键词
