Abstract

The history of the development of the 4 {pi} counting method is reviewed. The unique properties of the 4 {pi} counter system are described and the criteria are specified which place disintegration rate measurements, made with the system, on an absolute basis. The types of radioactive decay process to which the method is applicable are outlined, together with the various errors to which a given measurement is liable. Departure of response probability from unity, absorption of radiation in the source-mounting system, and source self-absorption are discussed in detail. (author) [French] L'auteur fait l'historique des progres de la methode de comptage 4 {pi}. Il decrit les proprietes remarquables du dispositif de comptage 4 {pi} et precise les conditions dans lesquelles les mesures du taux de desintegration se font avec ce dispositif sur une base absolue. Il donne un apercu des types de processus de desintegration radioactive, ainsi que de diverses erreurs auxquelles est sujette une mesure donnee. Il examine en detail le cas ou la probabilite de reponse s'ecarte de l'unite, l'absorption des rayonnements dans le support de la source et l'autoabsorption de la source.

(author) [Spanish] En la memoria el autor expone el desarrollo del metodo de recuento 4 {pi}. Describe las caracteristicas particulares de este metodo y explica las razones por las que las mediciones de la velocidad de desintegracion efectuadas segun ese procedimiento tienen un caracter absoluto. Se indican, asimismo, los tipos de procesos de desintegracion radiactiva a los que se puede aplicar el metodo, asi como los diferentes defectos de que puede adolecer una medicion determinada. Tambien se estudia detenidamente el caso en que la probabilidad de respuesta no es igual a la unidad, la absorcion de radiaciones en el soporte de la fuente y la autoabsorcion de la misma.
