What is neutron radiography? Neutron transmission radiography (NR) is based on the application of the universal law of attenuation of radiation passing through matter. Because different materials have different attenuation behaviour the neutron beam passing through a sample can be interpreted as a signal carrying information about the composition and structure of the sample. The basic experimental set-up is given by the following arrangement: source - collimator - object - collector.

neutron radiography: term standardized by ISO in 1998.

Radiographie effectuée à l'aide de neutrons.

CONT

La radiographie par émission de neutrons trouvera [...] des applications pour la détection de «pailles métalliques», de bulles d'air au sein d'une structure composite et même dans la détection d'assemblages imparfaits inhérents à ces nouveaux matériaux. Le cœur du nouveau système repose sur un modérateur/collimateur relié à un tube à neutrons qui [...] peut être stimulé ou arrêté instantanément.

OBS

neutronographie : terme et définition normalisées par l'ISO en 1997.
