由于快中子在物质中的良好穿透特性，快中子照相技术是一种很有吸引力的无损检测技术。然而，探测快中子的难度降低了这一吸引人的特征。作为克服这一困难的一种尝试，成像版被应用于快中子照相。用Yoneda等人提出的(快中子、热中子和伽马射线)FTG鉴别器对两片成像板和一片聚乙烯作为质子发射体的简单组合进行了检验。。实验结果表明，该方法能有效识别γ射线，适用于快中子照相。
Fast neutron radiography is an attractive non-destructive inspection technique because of the excellent penetration characteristics of fast neutrons in matter. However, the difficulty of detecting fast neutrons reduces this attractive feature. As an experiment to overcome the difficulty, imaging plates were applied to fast neutron radiography. A simple combination of two sheets of imaging plates and a sheet of polyethylene as a proton emitter was examined with the (fast neutron, thermal neutron and gamma ray) FTG discriminator proposed by Yoneda et al. . The experimental results showed that the method could be applicable to fast neutron radiography with effective discrimination of γ-rays
