AbstractAbstract
[en] Neutron radiography is a nondestructive testing technique similar to x-radiography that can have important advantages in many specific situations. Large thicknesses of some dense metals can be penetrated; high sensitivity can be obtained for small details containing hydrogen and certain other light elements; materials of similar density can be contrasted: and highly radioactive objects can be neutron radiographed without interference from the gamma radiation. During the decade 1965 to 1975, industrial application of neutron radiography has grown rapidly due to (1) availability of suitable neutron sources, (2) advancements of the techniques, and (3) widening appreciation of the capabilities. Over 100 centers are now performing neutron radiography. Most use neutron beams of predominantly thermal energy from a nuclear reactor source, but there are examples of different techniques, some using different neutron energies, and some using accelerator or isotopic neutron sources

AbstractAbstract
[en] The neutronographic product according to the invention comprises a means for absorbing neutrons and generate a current through the dissipation of electrostatic charges in proportion to the number of neutrons absorbed, said means for absorbing neutrons comprising an insulating layer containing a neutron absorbing agent at a concentration of at least 1017 atoms per ml. That product also comprises a conducting layer, a neutron source emits a neutron flux through an object so as to provide a neutronographic image on that product. This can be applied to the preparation of a direct neutronographic product which can be handled, exposed and developed in the presence of light and substantially insensitive to the gamma radiation usually associated to the radiations emitted by most neutron sources

Le produit neutronographique suivant l'invention comprend un moyen pour absorber les neutrons et produire un courant par dissipation de charges electrostatiques proportionnellement au nombre de neutrons absorbes, ce moyen d'absorption des neutrons comprenant une couche isolante qui contient un agent absorbant les neutrons a une concentration au moins egale a 1017 atomes par ml. Ce produit comprend, en outre, une couche conductrice. Une source de neutrons emet un flux de neutrons a travers un objet pour obtenir une image neutronographique sur le produit. Ceci est applicable a la preparation d'un produit neutronographique direct qui peut etre manipule, expose et developpe en presence de lumiere et qui est pratiquement insensible au rayonnement gamma qui est habituellement associe aux rayonnements emis par la plupart des sources de neutronsOriginal Title
Produit pour enregistrer une image par neutronographie directe et procede pour la mise en oeuvre de ce produit
