Annotation of standard text IEC 61526-ed.4.0 :
IEC 61526:2024 applies to personal dosemeters with the following characteristics: a) They are worn on the trunk, close to the eye, or on the extremities. b) They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes). c) They have a digital indication. This indication may or may not be attached. d) They have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters. For hybrid dosemeters an alarm function for the personal dose equivalents shall be implemented in the associated readout system. This document specifies requirements for the dosemeter and, if supplied, for its associated readout system. This document specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics. This edition includes the following significant technical changes with respect to the previous edition: a) Modification of the title; b) Inclusion of the measurement quantity for the dose in the lens of the eye, Hp(3); c) Inclusion of measurement quantity for dose in the skin and extremities, Hp(0,07); d) Inclusion of dosemeters between active and passive: "hybrid dosemeters"; e) Inclusion of software requirements; f) Harmonization of requirements for linearity to IEC 62387; g) Revised neutron energy response requirements. IEC 61526:2024 sapplique aux dosimetres individuels qui presentent les caracteristiques suivantes: a) ils sont portes sur la poitrine, pres des yeux, ou aux extremites; b) ils mesurent les equivalents de dose individuels Hp(10), Hp(3) et Hp(0,07) pour les rayonnements externes X et gamma, neutron (excepte Hp(3)) et beta, et peuvent mesurer les debits dequivalents de dose individuels respectifs pour les memes rayonnements (a des fins dalarme); c) ils comportent un affichage numerique. Cet affichage peut ou non etre inclus; d) ils ont des fonctions dalarme pour les equivalents de dose individuels ou pour les debits dequivalents de dose individuels, a lexception des dosimetres hybrides. Pour les dosimetres hybrides, une fonction dalarme pour les equivalents de dose individuels doit etre mise en ouvre dans le systeme de lecture associe. Le present document specifie les exigences pour les dosimetres et, sils sont fournis, pour leurs systemes de lecture associes. Le present document specifie, pour les dosimetres decrits ci-dessus, leurs caracteristiques generales, leurs procedures dessai generales, leurs caracteristiques sous rayonnement ainsi que leurs caracteristiques electriques, mecaniques, de securite et environnementales. Cette quatrieme edition annule et remplace la troisieme edition parue en 2010. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) modification du titre; b) introduction de la grandeur de mesure pour la dose dans le cristallin de loil, Hp(3); c) introduction de la grandeur de mesure pour la dose dans la peau et les extremites, Hp(0,07); d) introduction des dosimetres qui relevent des categories de dosimetres actifs et passifs: les "dosimetres hybrides"; e) introduction des exigences relatives au logiciel; f) harmonisation des exigences de linearite par rapport a lIEC 62387; g) revision des exigences de reponse a lenergie des neutrons.
