Abstract

The paper gives the main technical characteristics of gamma sources produced in the USSR using cobalt-60 and caesium-137 and discusses some of the problems of their production technology. The paper contains information on the radiation spectra of Co{sup 60} and Cs{sup 137} and of the source material from which they are prepared. Data are given on the dependence of the activity of cobalt sources upon the intensity of the neutron beam and the geometrical size of the sample. The yield of caesium by uranium fission is also analyzed. The problem of hermetic sealing of the sources is discussed and a complete nomenclature of all the sources manufactured in the USSR are listed, their size and activity also being indicated. In conclusion a comparison of Co{sup 60} and Cs{sup 137} sources is made.

On donne les resultats obtenus lors de l'etude de la variation de l'activite des sources au cobalt en fonction de la valeur du flux de neutrons et des dimensions geometriques de l'echantillon, ainsi que les resultats relatifs a la valeur du rendement en isotopes de cesium lors de la fission des noyaux d'uranium. On etudie ensuite les procedes pour assurer l'hermeticite de ces sources. Suit une nomenclature complete des sources produites en URSS, comportant des indications sur leurs dimensions geometriques et sur les valeurs de leur activite. Enfin, il est procede a une comparaison des sources au {sup 60}Co et au {sup 137}Cs. (author) [Spanish] En este informe se describen las principales caracteristicas tecnicas de las fuentes gamma de cobalto-60 y cesio-137 producidas en la Union Sovietica y se examinan algunos problemas de orden tecnologico planteados por su fabricacion. En el informe figuran una serie de datos sobre las propiedades de las radiaciones emitidas por las fuentes de {sup 60}Co y {sup 137}Cs y del material con que estas se fabrican. Se facilitan informaciones sobre la influencia que la magnitud del flujo neutronico y las caracteristicas geometricas de la muestra ejercen sobre la actividad de la fuente; el informe tambien contiene datos sobre el rendimiento de los distintos isotopos de cesio obtenidos por fision de los nucleos de uranio. Se examinan los procedimientos para encerrar hermeticament e las fuentes y se facilita una lista completa de las fuentes utilizadas en la Union Sovietica, con indicacion de sus caracteristicas geometricas y de su actividad. Por ultimo, se hace un estudio comparativo de las fuentes de {sup 60}Co y {sup 137}Cs.
