用铅吸收方法确定了几种G-M计数管(Philps)18509计数管、(Philps)18550计数管、J417计数管和FWT GM-2计数管)对D-T 14MeV快中子的相对灵敏度(K_α)。对实验数据的处理采用了与现有方法有所不同的方法,并与现有的方法进行了比较分析。对实验方法和数据处理中的有关问题进行了讨论。
The relative sensitivity (K_α) to D-T 14MeV fast neutron for several G-M count tubes (Philps) 18550 counter, J417 counter and FWT GM-2 counter tubes was determined by lead absorption. The experimental data is treated differently from the existing methods and compared with the existing methods. The experimental methods and data processing issues are discussed.
