ABSTRACT:
A source of neutrons is pulsed. A resultant flow of pulsed neutrons is detected and initiates a time delay. During the time delay, more quickly moving sources of radiation, such as fast and epithermal neutrons as well as gamma rays pass by an imaging device which is not turned on. Accordingly, these sources of noise are not detected. At the end of the time delay, the detecting imaging device is turned on; and during a resulting window interval, the pulsed thermal neutrons are detected and imaged after passage through an intermediately positioned object.
