In order to study the character of disturbing signals in the measurement of fast neutron field with FNS-100 proportional counter
spectra of the low energy gamma rays produced by 60Co as well as 7 MeV and 10 MeV high energy gamma rays are calculated and analyzed. In addition
the disturbance from 3He recoil and proton recoil are simulated. The results show that gamma rays give little effect on the measurement of fast neutron energy spectra
but 3He recoil and proton recoil have considerable effect on it.
