Annotation of standard text IEC 61577-3-ed.2.0 :
IEC 61577-3:2011 describes the specific requirements for instruments measuring the volumetric activity of airborne short-lived radon decay products and/or their ambient potential alpha-energy concentration outdoors, in dwellings, and in workplaces including underground mines. This standard applies practically to all types of electronic instruments that are based on grab sampling, continuous sampling technique and electronic integrating measurement methods. This new edition includes the following significant technical changes with respect to the previous edition: - implementation of new requirements and tests concerning radiation detection performance; - implementation of new requirements and tests concerning environmental performance; - harmonization of the requirements and tests concerning electrical and mechanical performance with other standards in the area of radiation protection instrumentation. La CEI 61577-3:2011 decrit les exigences specifiques relatives aux instruments destines au mesurage de lactivite volumetrique des descendants du radon a vie courte en suspension dans lair et/ou de leur energie alpha potentielle volumique a lexterieur, dans les habitations et sur les lieux de travail, y compris dans les mines souterraines. En pratique, la presente Norme sapplique a tous les types dinstruments electroniques utilisant des methodes basees sur un prelevement instantane, un prelevement en continu et des methodes de mesure electroniques integrees. Cette nouvelle edition constitue une revision technique et inclut les changements techniques significatifs suivants par rapport a ledition precedente: - ajout de nouvelles exigences et de nouveaux essais concernant les performances de detection de rayonnement; - ajout de nouvelles exigences et de nouveaux essais concernant les performances environnementales; - harmonisation des exigences et des essais, concernant les performances electriques et mecaniques, avec dautres normes du domaine de linstrumentation pour la radioprotection.
