Abstract

The report describes the principal requirements for gamma units intended for various purposes. Several methods of calculating the dose fields for various forms of irradiators are given, as well as graphs, nomograms and formulae to estimate the amount of gamma-ray dose absorbed by the irradiated object from cobalt-60 and caesium-137. Some of the calculated data have been confirmed by experiment. The advantages of irradiators of various geometry employed in experimental and commercial units are discussed. The irradiation technique for various objects is analyzed and the optimum irradiation conditions (radiation utilization factor, dose field homogeneity, etc.) are discussed. Several rational shielding systems are suggested to simplify irradiation process and recharging, and to reduce the cost of design and operation.

Certaines donnees etablies par le calcul ont ete confirmees experimentalement. On examine l'utilite d'employer des dispositifs d'irradiation de configurations variees dans des installations experimentales et des installations industrielles. Les auteurs examinent la technologie de l'irradiation de divers echantillons en vue de choisir les conditions optimales d'irradiation (facteur d'utilisation du rayonnement, uniformite du champ recevant une dose determinee, etc.). Quelques systemes rationnels de protection, simplifiant le processus d'irradiation, sont exposes ainsi que des methodes permettant un echange de charge dans les installations et reduisant le cout de la construction et de l'exploitation. (author) [Spanish] En este informe se indican los requisitos esenciales que deben reunir las instalaciones de irradiacion gamma destinadas a distintos usos. Se describen varios metodos para calcular campos de distintas intensidades en funcion de la forma de la fuente de cobalto-60 y cesio-137 empleada y se facilitan graficos, nomogramas y formulas que permiten determinar el valor de la dosis de rayos gamma absorbida por el objeto irradiado. Algunos de los datos calculados se han confirmado experimentalmente. Se examinan los usos mas convenientes de una serie de dispositivos de irradiacion de distintas configuraciones en instalaciones experimentales e industriales. Los autores estudian asimismo los procedimientos de irradiacion de diferentes muestras, que se aplican con el proposito de poder elegir unas condiciones de irradiacion optimas (coeficiente de aprovechamient o de la radiacion, uniformidad del campo de irradiacion, etc.), La memoria describe tambien algunos sistemas racionales de proteccion que simplifican las operaciones de irradiacion, asi como los dispositivos que permiten cambiar la carga y reducir de este modo los costos de construccion y de explotacion de las instalaciones.
