Active inspection techniques measure [either] delayed radiation, differential die-away, or prompt neutrons. Prompt neutrons are immediately emitted when fission occurs, as opposed to delayed low-energy neutrons and gamma rays, which are emitted by the fission products anywhere from milliseconds to seconds after the fission event. The differential die-away technique pulses neutrons into the cargo and monitors perturbations (if any) in the die-away characteristics of the normal neutron fluence rate that occur between neutron pulses. 3, record 1, English, - differential%20die%2Daway%20technique

[…] la méthode DDT permet d’atteindre de très basses limites de détection et ce, grâce à l’utilisation d’un générateur de neutrons (forte intensité interrogatrice [environ 108 à 2 X 109 nanosecondes exposant –1) associée à la mesure des neutrons prompts des fissions induites. 2, record 1, French, - m%C3%A9thode%20DDT
