Abstract
a. Procédé dans lequel on intercepte alternativement des champs de longueur d'onde différente d'un rayon d'intensité définie, on affaiblit l'intensité d'un des champs et on mesure l'intensité au moyen d'un détecteur. b. Procédé caractérisé en ce que pour plus de précision de la mesure, on rend le plus élevé possible le rapport signal/bruit du récepteur 7 et on compense sa superposition du signal de référence 20 du détecteur et du signal de mesure 21 qui le suit, par un choix, comme base d'intégration, d'une parallèle distante de la ligne de zéro 22 de sortie 20, 21 du détecteur. c. Procédé applicable à la détermination de la présence de fluorure d'uranium dans des gaz de réacteurs nucléaires.
