The idea of neutron methods for explosives detection was already being developed around the world at the end of the last century. Slower detection and health protection aspects resulted in the use of these devices not being widespread. However, “neutrons in, gamma out” methods are irreplaceable methods for bulk detection of explosives and other illegal organic materials in special cases. They are therefore suitable for higher levels of baggage security checks, cargo containers and improvised explosives devices.
