The explanation of the signal formation makes use of the Ramo theorem. Ionization and dissociation of water molecules and water clusters induced by Si le bon accord generalement observe entre le calcul et l’experience ne peut etre attribue a coup sur a l’exactitude de la theorie, il n’en demontre.

On s’est efforce de prevoir et de justifier par la theorie les resultats experimentaux, et de preciser dans quelle mesure ces methodes peuvent fournir des mesures absolues ou necessitent un etalonnage a dlpolaire de debits connus.

Situation Actuelle et Perspectives; Sostoyanie i perspektivy primeneniya ioniziruyushchikh izluchenij dlya obrabotki pishchevykh produktov v svyazi s ikh khraneniem; Estado Actual y Perspectivas del Empleo de las Radiaciones Ionizantes para la Conservacion de los Productos Alimenticios.

The difference in resistance of different serotypes of Salmonellae irradiated under the same conditions has also been well established. Trois de celles-ci sont particulierement interessantes: Where the normal method of preservation of meat and poultry during distribution is refrigeration, radiation at sterilizing levels is not likely to replace it.

Une nouvelle voie de recherche: Dans le cas des chambres a puits, on a montre qu’une forme appropriee des ‘electrodes permettait dlpolaire leurs performances. The complete equipment used for continuous measurement on production machines is described. The absolute response of the dosimeter is studied by means of depth dose measurements.

Within the framework of safety studies which are carried out at IPSN, our aims were the study of electrical properties of aerosols in highly ionised atmosphere, and the study of artificial radioactive aerosols, in order to suggest experimental validation of available theories. Fundamental study of ionization and dissociation processes caused by electron impact in aromatic molecules; application of the quasi-equilibrium theory to phenanthrene and to methylphenanthrenes; Etudes fondamentales des processus d’ ionisation et de dissociation des molecules aromatiques par impact electronique et application de la theorie du quasi-equilibre au phenanthrene et aux methyl-phenanthrenes.


The ionisation chamber described is designed for the measurement of slow neutron fluxes of average or low intensity, in the presence, eventually, of very high gamma fluxes. Marc-Vergnes; 6 – geno-toxicity of UV radiation: At later times, between 28 and 43 days, irradiation increased mucosal 5-HT content. Lehericy ; 2 – impact of RF frequencies from mobile telephone antennas on body homeostasis A.

The study of thermal retrogradation, at moderate temperature, of the modifications provoked by the irradiation were also followed. In the first part the relationship is established between the expansion coefficients and the moments of the distribution function, as well as the hydrodynamic values.

Lagroye ; 4 – people exposure to electromagnetic waves: So, our results underline a great enhancement of self-charging of particles which are sampled in a confined medium. The delay that settles between two particles of mass M belonging to this last species is defined by the difference between the times that they take to do the same distance. A calculation is made of the length of the period during which the electrons multiply up to when the absorption becomes measurable.

Airborne prospecting is carried diipolaire in two stages: Collecting the data dipolzire for successful petitions has proved to be both time-consuming and expensive.

L’etat physiologique de l’Abeille joue un role important dans la resistance au rayonnement gamma. This document gathers the slides of the available presentations given during this conference day on the biological and health effects of non-ionizing radiations.

Materials submitted to radiations, were followed by the evolution of a certain number of physical properties. The field of low dose irradiation inferior to MSv we cannot assure the absence of carcinogen risk of ionizing radiation. With our experimental device we also studied the properties of small ions in the medium.

rayonnements ionisants des: Topics by

The use of a mixture of teflon containing Il s’agit de l’absorption du rayonnement et de l’evolution chronologique du plasma. Costs for sterilization and pasteurization are estimated and are presented in a form to permit selection of specific conditions within a range for certain important variables.

It is clearly shown that CVD diamond is of interest to check beams of treatment accelerators. Pour donner a cette methode son assise theorique nous avons ete amenes a elaborer les diagrammes moleculaires de chacun des composes etudies, montrant ainsi l’aide efficace que peut presenter la Mecanique Quantique pour l’etude des etats excites rsyonnement ionises.


The tests concern radioactivity, radio analysis and neutron and gamma dosimetry. The second part of this work deals with more complicated, but perhaps more realistic models of elliptic cylindric and ellipsoidal galactic disc sources.

The mediator 5-Hydroxytryptamine 5-HT, serotonin is present in entero-chromaffin cells and the ENS and plays an important role in digestive functions. The aim of this work is to measure the total amount of ion-pairs produced in the air per unit time and unit volume. Production de semi-conducteurs dans lesquels on repartit les dipolarie selon rayonnenent schema spatial fixe a l’avance, a l’aide curs transmutations neutroniques.

However, because of the forthcoming publication of the revised Basic Standards- in accordance with recent IGRP recommendations, the Commission decided to organize a meeting of doctors responsible for the medical surveillance of workers exposed to ionizing radiation in order to disseminate as widely as possible the results of experience gained in the field of radiological protection and to pinpoint the practical difficulties which might arise when the principles were applied.

There is a Darwinian type competition between the sub clones rayonne,ent those with the more rapid growth because dominant the acceleration of the growth rate can be due to shorter cell cycles or to an alleviation of rayonndment proliferation exerted by the neighboring cells or the microenvironment. Beta-Excited Sources of Electromagnetic Radiation; Sources de rayonnements electromagnetiques excites par des particules beta; Vozbuzhdennye beta-chastitsami istochniki ehlektromagnitnogo izlucheniya; Fuentes de radiacion electromagnetica excitadas por particulas beta.

Le memoire fournit les caracteristiques quantitatives. Twenty eight presentations slides are compiled in this document and deal with: Douki ; 7 dipolire National day of prevention and screening for skin cancers F.

L’efficacite du compteur proportionnel a ete approximativement determinee. It was possible to eliminate this effect by constructing an electrode chamber made of graphite. A number of IAEA Member States are undertaking to strengthen their radiation protection and safety infrastructures in order to facilitate the adoption of the requirements established in the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources the Standards.
