Abstract

The possibility of using alpha-radiation for industrial measurement of the surface weight of thin materials has been mentioned by several authors. The techniques have been adapted for industrial use thanks to research on new equipment which, while employing standard techniques, was specially designed for alpha-radiation. To compensate for variations in the absorbent capacity of the source-detector interval, a two-path differential method must be used. By alternate feeding of the ionization chambers, alternate amplification and detection circuits can be used without prior conversion of the ionization current. The measurement range is 6 to 55 g/m{sup 2} and measurement is accurate to 1% in conditions of perfect stability. The complete equipment used for continuous measurement on production machines is described. The technique can also be used with beta-radiation.

L'emploi d'une methode differentielle a deux trajets est indispensable pour la compensation des variations de pouvoir absorbant de l'intervalle source-detecteur. L'alimentation en alternatif des chambres d'ionisation permet l'utilisation de circuits alternatifs d'amplification et de detection sans conversion prealable du courant d'ionisation. La gamme de mesure s'etend de 6 g a 55 g/m{sup 2} avec line precision de 1% dans des conditions de parfaite stabilite. On decrit le dispositif complet utilise pour les mesures en continu sur les machines de production. Cette technique est egalement utilisable pour les rayonnements beta. (author) [Spanish] Diversos investigadores ya han mencionado la posibilidad de emplear los rayos alfa para llevar a cabo mediciones industriales del peso por unidad de superficie de materiales de espesor reducido. El aprovechamiento industrial de estas tecnicas pudo desarrollarse gracias al perfeccionamiento de nuevos aparatos que, si bien aplican tecnicas tradicionales, fueron especialmente disenados para el empleo de rayos alfa. Para compensar las variaciones de la capacidad de absorcion en el intervalo que media entre la fuente y el detector, es indispensable emplear un metodo diferencial de dos recorridos. La alimentacion de las camaras de ionizacion con corriente alterna permite utilizar circuitos de amplificacion y de deteccion alternos sin necesidad de transformar previamente la corriente de ionizacion. El intervalo de medicion abarca de 6 a 55 gramos por metro cuadrado, con una aproximacion del 1 por ciento en condiciones de perfecta estabilidad. Los autores describen el dispositivo completo utilizado para efectuar mediciones continuas en las maquinas industriales. La tecnica descrita puede adaptarse igualmente a los rayos beta.
