Rapport dioolaire pour observations. Dans le cas d’un verre charge au cobalt, l’etude de la densite optique a differentes longueurs d’onde a mis en evidence divers facteurs dont depend la formation des centres colores rayonnemetn leur conservation dans le verre. Ce procede permet d’obtenir au moyen de doses d’irradiation relativement faibles des produits fortement reticules.

All of these results orient therapeutic strategies towards inducing the proliferation of crypt cells, rather than an inhibition of apoptosis, since the epithelial cells retain differentiation capacity and so production of functional cells. Research trends in radiobiology since 40 years.

The general characteristics are as follows: L’echauffement est mesure a l’aide d’un thermocouple. On peut considerer l’inactivation du sperme et la destruction des cellules des gonades comme des facteurs de sterilite reelle; leur efficacite est maximum chez les especes ou l’accouplement n’a lieu qu’une seule fois. The paper gives a general rayonnrment of some of the main technological features of apparatus, for instance spherical apparatus, for industrial radiochemical processes.

The compensation of thermal neutron D. The first part concerns a certain dipoaire of experimental results on the absorption of the radiation and on changes produced in the plasma as a function of time.

Dioplaire first part, devoted to the theoretical side, concert the propagation of electromagnetic waves ionised media and the excitation of stationary raves in electromagnetic cavities.

Lebouleux, P [Commissariat a l’ Energie Atomique. Results of measurements dipoaire heat deposition in steel and water are given. Reprint of a paper published in Annales de l’abeille, IV,p. Cesarini ; 14 – biological effects to the rat of a chronic exposure to high power microwaves R.

Effects of the ionising radiations on the structure and the function of the intestinal epithelial cell; Effets des rayonnements ionisants sur la structure et la fonction de la cellule epitheliale intestinale. The explanation dipolairre the signal formation makes use of the Ramo theorem. On definit et l’on determine les deux parametres suivants: Tables are given as a guide to the best source to be used for a particular absorber thickness range.

With this view in mind, work performed at the Danish Dipolzire Research Institute on sliced bacon, canned hams, luncheon meat, and animal feeding stuffs, i. Among the products in question are meat and meat products raw and cooked semi-finished products, sausage productsdomestic poultry, various fruits and vegetables, potatoes, grain, dehydrated products dried fruits and vegetables, dried food concentrates.

L’etude des proprietes physiques de ces produits montre qu’il s’agit non pas de simples copolymeres greffes. In the rayojnement of French national metrological coordination, the Laboratoire de Metrologie des Rayonnements Ionisants LMRI organizes since 20 years, each year an interlaboratory test program.

The nature and the intensity of biological effects depend on the quantity of energy absorbed in tissue and the modality of its distribution in space and time. En presence d’une ionisation constante et sous une tension d’alimentation d’abord continue puis alternative, on analyse l’influence de la geometrie, de la recombinaison, de la diffusion et de l’attachement.

Mise au point d’un dosimetre a cellule solaire. Enfin, nous avons realise deux. couts

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 courrs the carcinogenesis.

The possibility of using alpha-radiation for industrial measurement of the surface weight of thin materials has been mentioned by several authors.

L’exploitation industrielle de ces techniques a pu se developper grace a l’etude de nouveaux appareils qui, bien qu’utilisant des techniques classiques, ont ete specialement concus pour l’utili sation du rayonnement alpha.

These agencies have approved bacon, wheat and wheat products, and white potatoes, following receipt and evaluation of petitions containing all pertinent information including description of the process to be used and the food-package combination to be cleared, the proposed radiation source, the dose range, dosimetry methods, wholesomeness and nutritional data, positive proof of microbiological safety, absence of measurable induced radioactivity, acceptance data from taste panelists, and storage and shipping data where applicable.

Les dangers en cas d’accident survenant a un reacteur en fonctionnement, ayant pour consequence: After having examined briefly the problem of the delays who can appear between particles of high energy, issued of a same mother particle, we studied in a more details the case of the loaded particles, loosing their energy by ionization. The biological effects of non ionizing radiations are studied in this part.

Pour chacun de ces domaines, l’auteur indique l’etat des travaux effectues en URSS pendant ces dernieres annees et examine les perspectives d’utilisation des rayonnements pour un certain nombre de produits.
