[...] il est possible d'étudier la répartition de certains éléments en utilisant les particules émises en cours d'irradiation à partir de ces éléments. La méthode dite des traces nucléaires, encore connue sous le nom de NCR (neutron capture radiography) s'apparente à celle de l'autoradiographie, mais ici le détecteur est un minéral ou un film organique (le plus souvent nitrate de cellulose) irradié plaqué sur l'échantillon à analyser. Contrairement aux films photographiques, ces détecteurs ne sont pas sensibles aux rayons ß et [gamma]. Les dommages engendrés dans ces détecteurs par les particules émises pendant l'irradiation (protons, [alpha]) sont révélés après irradiation par attaque chimique, comme pour les traces de fission. 1, record 1, French, - m%C3%A9thode%20des%20traces%20nucl%C3%A9aires

BNCT depends on the interaction of slow neutrons with boron-10 to produce alpha particles and lithium nuclei, without producing other types of ionizing radiation. Patients are first given an intravenous injection of a boron-10 tagged chemical that preferentially binds to tumor cells. 1, record 3, English, - boron%20neutron%20capture%20therapy

[...] une équipe multidisciplinaire du Centre atomique de Bariloche de la Commission nationale de l'énergie atomique (CNEA) [...] vient de réaliser le premier essai clinique en Amérique latine de thérapie par capture de neutrons par le bore (BNCT). Dans ce traitement, une substance inerte qui se loge sélectivement dans les cellules tumorales est injectée au patient qui subit ensuite une exposition à des neutrons de basse énergie. Le bore présent dans les cellules absorbe les neutrons qui, par fission nucléaire, émettent une radiation qui traverse une distance équivalente au diamètre de la cellule tumorale pour la détruire. Le bore se concentre 5 fois plus au sein des cellules tumorales que dans les cellules saines et cette méthode BNCT est donc considérée comme moins invasive pour les tissus normaux. 2, record 3, French, - th%C3%A9rapie%20par%20capture%20de%20neutrons%20par%20le%20bore
