CONT

The skin dose (surface dose) is the radiation delivered at the skin. It is the sum of the dose from the incident radiation plus the dose from the backscatter radiation.

CONT

Skin dose. The limit for skin is set by reference to deterministic(formerly known as non-stochastic) effects. These are effects such as reddening or ulceration of the skin which vary in intensity in proportion to the dose, and also have a threshold dose below which no effects appear. The proposed limit, which is below the threshold, is 500 mSv in any dosimetry year, averaged over any 1 cm² area at a nominal depth of 7 mg cm², regardless of the area exposed.

CONT

La limite de la dose à la peau est fixée par référence aux effets déterministes (anciennement non stochastiques). Ce sont des effets comme le rougissement ou l'ulcération de la peau dont l'intensité est proportionnelle à la dose et pour lesquels il existe un seuil de dose sous lequel aucun effet se manifeste. La limite proposée, soit 500 mSv par année de dosimétrie, est inférieure à ce seuil et est établie selon une moyenne calculée sur une superficie de 1 cm² à une profondeur nominale de 7 mg cm², peu importe la superficie exposée.

CONT

Call agent is the term used to describe the basic MGC [media gateway controller] functionality needed to set up and tear down calls, and to maintain details of the state of each call. The call agent interacts with the signaling protocols that exist on either side of MG [media gateway] for the purposes of coordinating call setup and teardown.

  • Mineralogy
CONT

X-ray powder diffraction is used in the identification of crystalline phases in unknown samples, finding the lattice parameter and other lattice related information, quantitative determination of phases in multiphase samples, finding the orientation in single crystals, and stereographic projections. The samples must be crystalline solids such as metals, ceramics, rocks etc. These samples are usually about 1 mg in size. If the sample fits in the sample holder then there is no preparation necessary otherwise the sample may have to be crushed in order to fit. The sample takes less than one hour to be analyzed for qualitative analysis in major phases and up to 16 hours for trace phases. The quantitative analysis can take several minutes to several hours after set up. There are several detectors used in XRPD varying from films to cameras to diffractometers.

CONT

Powder X-Ray Diffraction. Powders of crystalline materials diffract X-Rays. A beam of X-rays passing through a sample of randomly-oriented micro-crystals produces a pattern of rings on a distant screen. Powder X-Ray diffraction provides less information than single-crystal diffraction, however, it is much simpler and faster. Powder X-Ray diffraction is useful for confirming the identity of a solid material and determining crystallinity and phase purity. Modern powder X-Ray diffractometers consist of an X-Ray source, a movable sample platform, an X-Ray detector, and associated computer-controlled electronics. The sample is either packed into a shallow cup-shaped holder or deposited as a slurry onto a quartz substrate, and the sample holder spins slowly during the experiment to reduce sample heating. The X-Ray source is usually the same as used in single-crystal diffractometers, Mo or Cu. The X-Ray beam is fixed and the sample platform rotates with respect to the beam by an angle theta. The detector rotates at twice the rate of the sample and is at an angle of 2 theta with respect to the incoming X-Ray beam.

CONT

Fine particles such as clays must be separated from larger particles and measured separately if they are to be detected properly. To reduce errors associated with preferred orientation of minerals, samples are most commonly ground to a powder before analysis, a technique known as powder X-ray diffraction.

CONT

X-ray powder diffraction (XRD) is a direct method for qualitative and quantitative characterization of fine-grained materials such as clinker and cement, and may also be used for analysis of raw materials. Each phase produces a unique diffraction pattern independent of others, with the intensity of each pattern proportional to that phases concentration in a mixture.
