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

Decay is associated with the loss of the radioactive isotope and the formation of another isotope of the same element but of lower mass, or the formation of one or more different elements. The rate of decay is proportional to the amount of the radioactive isotope present in the sample and is characterized in terms of its half-life. The half-life is the time taken for the radioactivity to decay to 50% of its original activity. 7, record 3, English, - radioactive%20decay

The word radiation is commonly used in several distinct although related senses.-First, it is a term for the process by which energy is transferred and is able to exert an effect at a distance without the need for any physical connection between source and receiver. In this broad sense, radiation includes energy transfer both by electromagnetic waves(as in the case of gamma rays, ultra-violet rays or radio waves) and by energetic particles(such as alpha or beta particles emitted from nuclei in the process of radioactive decay). The more precise terms "electromagnetic radiation" and "particulate radiation" differentiate between these two phenomena. 2, record 5, English, - corpuscular%20radiation

The method by which incident radiation interacts with the medium to cause ionization may be direct or indirect. Electromagnetic radiations (X rays and gamma photons) are indirectly ionizing; that is, they give up their energy in various interactions with cellular molecules, and the energy is then utilized to produce a fast-moving charged particle such as an electron. It is the electron that then secondarily may react with a target molecule. Charged particles, in contrast, strike the tissue or medium and directly react with target molecules, such as oxygen or water. These particulate radiations are directly ionizing radiations. 1, record 17, English, - gamma%20photon
