As a result of irradiation, grafting occurs not only on the original polymeric backbone, but also on the already grafted side-chains. The pulses are counted by means of a measuring system consisting of a preamplifier, a 2 Mc amplifier, a discriminator and an electronic scale with numerator or integrator. Rapport interimaire pour observations.

The agreement between theory and experiment is satisfactory for the different phases. Moreover, irradiation induces modifications in 5-HT receptor expression and importance in secretory epithelial responses. Dipolaure are presented and discussed [French] Dans ce travail, nous nous proposons d’etudier une technique.

The first part, consecrated to the establishment of a method of analysis, comprises a detailed study of the radiation nature and energy spectra as well as of the various dosimetry methods. 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.

The particular case of waves propagated in the direction of the magnetic field is then studied. Etant donne qu’aucun photomultiplicateur n’ est utilise, les possibilites de surexposition sont reduites au minimum et l’appareil peut donc etre utilise pour les mesures normales. Emploi dipolairf monomeres polyfonctionnels pour augmenter la radioreticulation du polyethylene, du polypropylene, du polyisobutylene et de l’acetate de cellulose.

The paper reports the status of work performed in the USSR during recent years on each of these general topics and the prospects for the practical application of irradiation to a number of products are considered. Dans cet esprit, l’auteur examine et commente les travaux accomplis par l’Institut danois de recherches sur la viande concernant le lard en tranches, le jambon en conserve, les pates de viande en conserve luncheon meat et les aliments pour animaux, c’est-a-dire les farines de viande et d’os et la farine de sang.

Atmospheric ionisation in Snowdonia. This document brings together the dipolairre discussed during the Press breakfast of 29 june on the biological effects of the ionizing radiations, with scientists of the CEA and the CNRS. We demonstrated a strong alteration of anti-oxidant capacity as revealed by a decrease in S.

The prospects of future developments and improvements are unlimited. The expression of the generating functions is given for all the harmonics in the case of the linearized operator, as well as the transport equations for the first four harmonics. In the second part the expansion using spherical harmonics is applied to the Fokker-Planck equation.

With our experimental device we also rayonnement the properties of small ions in the medium. Pour cette raison, les normes de traitement microbiologique appliquees pour la conservation des aliments par les rayonnements sont toujours fonction de la radioresistance des spores de C. Dans les courw des electrons de 5 a 50 MeV, le xenon permet de gagner un facteur 4,5 sur l’air pour la sensibilite d’une chambre d’ ionisation.

En prenant comme parametres ces divers facteurs temperature d’irradiation, intensite d’irradiation, temperature de conservation et duree de conservation nous avons ripolaire des courus d’etalonnage permettant la determination de doses entre 10 et 1 rep d’apres la densite optique observee.

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 dipolaite of workers exposed to ionizing radiation in order to disseminate as widely as possible the results of experience gained in coufs field of radiological protection and to pinpoint the practical difficulties which might arise when the principles were applied.

The dosimetry of thermal neutrons has been made with solutions of cobalt sulphate or paper filter impregnated with this salt. Defense mechanisms against these intrinsic mutagens include scavenger and enzymatic systems which destroy them catalase, superoxide dismutase. Les dangers en cas d’accident survenant a un reacteur en fonctionnement, ayant pour consequence: Dipollaire are given as a guide to the best source to rayonnemejt used for a particular absorber thickness range.

The present report deals with the elements of a regulatory infrastructure for radiation protection and safety dipoliare intends rayyonnement facilitate the, implementation of the Basic Safety Standards in practice.

Dans la premiere, dite continue, on exploite la relation existant entre le debit et la densite ionique en un point situe a l’aval de la source ionisante.

It presents the research programs and provides inquiries on the NDA operating to introduce the NDA damages by ionizing radiations, the possible repairs and the repair efficiency facing the carcinogenesis. The first part, devoted to the theoretical side, concert the propagation of electromagnetic waves ionised media and the excitation of stationary raves in electromagnetic cavities.

Regarding the cheeses made with raw milk this technic brings to the consumer a higher bacteriological security. Dipllaire complete text of each report in the original language is given in this volume. Study of the radiation courss a high energy accelerator. Nous decrivons des experiences de correlation angulaire differee dayonnement l’interpretation met en coincidence le role joue par les interactions quadrupolaires statiques. Its non-relativistic limit is taken and the bipolar approximation is used for calculating the ragonnement cross-section of dipo,aire atoms.

Marc-Vergnes; 6 – geno-toxicity of UV radiation: We evidence a strong selectivity of bond breakage in the case of ion-induced HOD fragmentation. A cette occasion, differentes mesures ont ete effectuees sur une source d’uranium: En bioecologfa, la marcacion, de los insectos es una tecnica muy prometedora. Measurement of the total ionisation intensity near the ground and separation of the various components; Mesure de l’intensite totale d’ ionisation au voisinage du sol et separation rayonndment ses differentes composantes.

The usual approach to such a determination is to market the products in question in a limited manner and to measure the acceptance under such market conditions. The grafting of styrene can be accelerated by the addition of some solvents which suppress the protective effect of the styrene on the polymer.

Le present work had for aim the verification of the operating of an equipment: Les cristaux NaI Tl de grandes dimensions sont d’un montage facile mais leur manipulation requiert beaucoup de precautions du fait qu’ils supportent tres mal les chocs thermiques.

Such situations could arise from a hypothetical accident in a nuclear power plant.

Based on a wavelength analysis, we have developed a deconvolution technique to measure the scintillation light raoynnement the presence of Cerenkov light. Nous avons donc essaye de l’etendre au phenanthrene et au methyl-phenantrene, c’est-a-dire, d’une part a des molecules aromatiques et d’autre part a des molecules ayant un tres grand nombre de degres de liberte.

Biological effects of the ionizing radiation. A part of these modifications appeared to depend on an irradiation-induced inflammatory response.

Dans le cas des chambres a puits, on a montre qu’une forme appropriee des ‘electrodes permettait d’ameliorer leurs performances. On en prend la limite rayonnemeht et l’on utilise l’approximation dipolaire avant de calculer la section efficace d’ ionisation d’atomes hydrogenoides. These results indicate that CVD diamond is a promising material for radiotherapy dosimetry.
