Instrumental neutron activation analysis(INAA) is used to determine the concentration of trace and major elements in a variety of matrices. A sample is subjected to a neutron flux and radioactive nuclides are produced. As these radioactive nuclides decay, they emit gamma rays whose energies are characteristic for each nuclide. Comparison of the intensity of these gamma rays with those emitted by a standard permit a quantitative measure of the concentrations of the various nuclides. 2, record 1, English, - instrumental%20neutron%20activation%20analysis

L'évolution des performances de l'analyse par activation neutronique instrumentale ou INAA est étroitement liée à celle des appareils de mesure et en particulier à celle des moyens de détection. Les développements de la spectrométrie gamma à haute résolution, dus à l'utilisation des détecteurs semiconducteurs, ont fait de l'INAA une méthode non destructive, très sensible et multiélémentaire, très efficace pour le dosage des éléments en trace dans les matériaux géologiques. 2, record 1, French, - analyse%20par%20activation%20neutronique%20instrumentale

Análisis por activación neutrónica instrumental (AANI) [...] es una técnica de referencia multielemental, de elevada sensibilidad, precisión y selectividad. No destruye la muestra y requiere pequeñas masas [...] Entre las ventajas del AANI cabe mencionar además que es una técnica no destructiva, de aplicación en muestras biológicas sin digestión ácida previa y en suspensiones y soluciones no acuosas, a la vez que se pueden analizar muestras de matrices muy diversas utilizando la misma metodología. Por otro lado, los límites de detección son significativamente inferiores a los permitidos por la espectrofotometría de absorción atómica. 1, record 1, Spanish, - an%C3%A1lisis%20por%20activaci%C3%B3n%20neutr%C3%B3nica%20instrumental

The COS-B satellite will carry a single large experiment, capable of detecting gamma-rays with energies in excess of 20 MeV in order to study in detail the sources of extraterrestrial gamma radiation. The principal objectives of the study will be to investigate the angular structure of gamma-ray emission from the galactic plane, to measure the flux of the isotropic radiation from high galactic latitudes believed to be of extra-galactic origin, to examine known or postulated point sources of the radiation and to determine the energy spectra of all identified sources. 3, record 4, English, - extraterrestrial%20gamma%20radiation
