The neutron detection systems for the measurement covering wide energy range from thermal to fast region has been successively developed. The main part of this system is made of organic scintillators (both liquid and plastic) with doped 10B, so that it should be sensitive to thermal neutrons with (n,) reaction while it could detect signals during degrading fast neutrons within the scintillator. This principle was verified. Also another system made of inorganic crystals was verified to see the capability to be used as a neutron detector.
