Radiative absorption properties of a number of propellants have been determined in the visible and near UV spectral regions. These data are required for evaluating the radiation energy distribution within a bed from a plasma. These data and a radiation propagation code(Monte Carlo, non-sequential ray tracing) will be used to determine the radiative energy distribution within a propellant bed. Heat flux/fluence gages are described that will be used to measure and differentiate between the convective and radiative energy delivered to a propellant bed.  1, record 1, English, - radiative%20propagation%20code

Pour être utilisables dans les codes de propagation des rayonnements, les sections efficaces doivent obligatoirement subir un traitement à la fois physique, numérique et informatique. Celui-ci découle de la nature des informations stockées dans les évaluations, de la nature du problème physique étudié et des méthodes numériques implémentées dans les codes de transport utilisés.  1, record 1, French, - code%20de%20propagation%20des%20rayonnements

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 2, English, - gamma%20photon

The third step is to fuse two tritium nuclei into one helium and two proton products. The end result of fusing four hydrogen nuclei(protons) is one helium nucleus, and two gamma ray photons, and two electron neutrinos, and kinetic heat energy.  2, record 2, English, - gamma%20photon

Gamma rays: A very penetrating electromagnetic radiation emitted from a nucleus of an atom during radioactive decay. Radiation: An emission of energy in the form of photons (gamma, x-rays) or particles (alpha, beta, positron, neutron radiation). Photon: A type of radiation in the form of an electromagnetic wave, having zero mass and zero charge.  3, record 2, English, - gamma%20photon

R. T. Co. researchers identified an innovative technology, the Remote Field Eddy Current technique(RFT), and during the past ten years have successfully incorporated it into a variety of tools for the inspection of heat exchangers, boilers, reactors, pipelines, downhole casing and water lines... Field operations consist of 20 truck-mounted units used for radiographic inspections of new pipelines and related facilities using internal crawlers and external gamma ray methods. In-house manufacturing capabilities include electromagnetic probe fabrication and light machining, as well as electronic board preparation and final system assembly.  2, record 3, English, - electromagnetic%20probe

Appareil émettant une onde électromagnétique. Au fur et à mesure que l'appareil avance dans la conduite, toute anomalie métallurgique de la paroi (ex. : usure) affecte le temps de propagation et l'amplitude de l'onde. La paroi de la conduite est donc auscultée de façon continue. Cette technique permet d'identifier les pertes de métal.  1, record 3, French, - sonde%20%C3%A9lectromagn%C3%A9tique
