Radiation protection instrumentation - Measurement of personal dose equivalents Hp(10) and Hp(0,07) for X, gamma, neutron and beta radiations - Direct reading personal dose equivalent meters

IEC 61526:2010 specifies general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings and those which concern the influence of the reader on the dosemeter. This new edition includes the following significant technical changes with regard to the previous one:
- improved determination of constancy of the dose response and statistical fluctuations;
- abolition of classes of personal dose equivalent meters in relation to retention of stored information;
- inclusion of usage categories of personal dosemeters.

Instrumentation pour la radioprotection - Mesure des équivalents de dose individuels Hp(10) et Hp(0,07) pour les rayonnements X, gamma, neutron et bêta - Appareils de mesure à lecture directe de l’équivalent de dose individuel

La CEI 61526:2010 spécifie les caractéristiques générales, les procédures générales d'essai, les caractéristiques sous rayonnement ainsi que les caractéristiques électriques, mécaniques, de sécurité et environnementales. Les seules exigences spécifiées pour les systèmes de lecture associés sont celles qui concernent l'exactitude de la lecture de l'équivalent de dose individuel et du réglage des alarmes et les exigences qui concernent l'influence du lecteur sur le dosimètre. Cette nouvelle édition comprend les principales modifications techniques suivantes par rapport à la précédente édition:
- amélioration de la détermination de la constance de la réponse de dose et des fluctuations statistiques;
- suppression des classes d'appareils de mesure de l'équivalent de dose individuel en fonction de la conservation des informations;
- inclusion de catégories d'utilisation pour les dosimètres individuels.

Instrumenti za zaščito pred sevanjem - Merjenje osebnih ekvivalentnih doz Hp(10) in Hp(0,07) za rentgenska (X), gama, nevtronska in beta sevanja - Osebni dozimetri z neposrednim odbiranjem

Standard IEC 61526:2010 določa splošne lastnosti, splošne preskusne postopke, sevalne, električne, mehanske, varnostne in okoljske lastnosti. Edine zahteve za povezane sisteme odbiranja so zahteve, ki vplivajo na točnost odbiranja osebne ekvivalentne doze in nastavitev alarma, ter zahteve, ki se nanašajo na vplivanje bralnika na dozimetru. Ta nova izdaja glede na prejšnjo vključuje naslednje pomembne tehnične spremembe:
– boljše določanje stalnosti učinka doze in statističnih nihanj;
– odprava razredov merilnikov osebne ekvivalentne doze v zvezi s hrambo shranjenih informacij;
– vključitev kategorij uporabe osebnih dozimetrov.
