Anotation

IEC 60806:2022 is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES. This document specifies a method for the determination of the greatest geometrically symmetrical RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE along the major axes of the RADIATION FIELD does not fall below a permitted value. In case multiple FOCAL SPOTS are not super-imposed, each FOCAL SPOT has its own REFERENCE AXIS. Then the maximum RADIATION FIELD can be given for each FOCAL SPOT separately. IEC 60806:2022 cancels and replaces the first edition published in 1984. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: a) addition of solid state detectors as they have become more common since the first edition of 1984. LIEC 60806:2022 sapplique aux ENSEMBLES RADIOGENES et aux GAINES EQUIPEE. Le present document specifie une methode pour la determination du plus grand CHAMP DE RAYONNEMENT de geometrie symetrique a une distance specifiee du FOYER pour laquelle le pourcentage de DEBIT DE KERMA dans l’air le long des axes principaux du CHAMP DE RAYONNEMENT, ne diminue pas pour atteindre une valeur inferieure aux valeurs autorisees. Sil ny a pas superposition de FOYERS multiples, chaque FOYER possede son propre axe de reference. Ainsi, le CHAMP DE RAYONNEMENT maximal peut etre donne individuellement pour chaque FOYER. LIEC 60806:2022 annule et remplace la premiere edition parue en 1984. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout des detecteurs a semiconducteur dont lusage sest repandu depuis la premiere edition de 1984.
