A method for detecting photonuclear-induced delayed neutrons emitted from a material by exciting the material with high-energy photon stimulation to generate neutrons emissions, detecting said neutrons, generating electric pulse signals representative of detected neutrons, amplifying and shaping said electric pulse signals with an amplifier, low-pass filter and high-pass filter, and comparing said amplified and shaped electric pulse signal with a threshold voltage to generate output pulses to detect delayed neutrons.
