摘要
讨论了低水平γ射线测量中所面临的本底问题。涉及屏蔽材料的选择、屏蔽体的结构以及主动屏蔽与被动屏蔽的方法和技术。对宇宙射线、环境本底、射线的能量发散等方面的影响都做了尽可能详尽的探讨。
This paper probes into the background issues which exist in the Measurement of Low-level. It involves the choice of the shield material, the structure of the shield as weIi as the methods and techniques of active shield and passive shield. It also gives a detailed discussion in the effects of cosmic-ray, environmental radionuclide, energy scattering, etc.
