Radiation protection instrumentation - Radon and radon decay product measuring instruments - Part 3: Specific requirements for radon decay product measuring instruments
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.

Instrumentation pour la radioprotection - Instruments de mesure du radon et des descendants du radon - Partie 3: Exigences spécifiques concernant les instruments de mesure des descendants du radon
La CEI 61577-3:2011 décrit les exigences spécifiques relatives aux instruments destinés au mesurage de l'activité volumétrique des descendants du radon à vie courte en suspension dans l'air et/ou de leur énergie alpha potentielle volumique à l'extérieur, dans les habitations et sur les lieux de travail, y compris dans les mines souterraines. En pratique, la présente Norme s'applique à tous les types d'instruments électroniques utilisant des méthodes basées sur un prélèvement instantané, un prélèvement en continu et des méthodes de mesure électroniques intégrées. Cette nouvelle édition constitue une révision technique et inclut les changements techniques significatifs suivants par rapport à l'édition précédente: - ajout de nouvelles exigences et de nouveaux essais concernant les performances de détection de rayonnement; - ajout de nouvelles exigences et de nouveaux essais concernant les performances environnementales; - harmonisation des exigences et des essais, concernant les performances électriques et mécaniques, avec d'autres normes du domaine de l'instrumentation pour la radioprotection.
Instrumenti za zaščito pred sevanjem - Instrumenti za merjenje radona in njegovih razpadnih produktov - 3. del: Posebne zahteve za instrumente za merjenje razpadnih produktov radona
Standard IEC 61577-3:2011 opisuje posebne zahteve za instrumente, ki merijo volumetrično dejavnost kratkotrajnih razpadnih produktov radona v zraku in/ali njihove okoljske potencialne koncentracije alfa energije na prostem, v stanovanjih ter na delovnih mestih, vključno s podzemnimi rudniki. Ta standard se uporablja za skoraj vse vrste elektronskih instrumentov, ki temeljijo na zajemnem vzorčenju, tehniki neprekinjenega vzorčenja in metodah elektronskega integrirnega merjenja. Ta nova izdaja vključuje naslednje znatne tehnične spremembe glede na prejšnjo izdajo:
– izvajanje novih zahtev in preskusov v zvezi z učinkovitostjo zaznavanja sevanja;
– izvajanje novih zahtev in preskusov v zvezi z okoljsko učinkovitostjo;
– usklajevanje zahtev in preskusov v zvezi z električno in mehansko učinkovitostjo z drugimi standardi na področju instrumentov za zaščito proti sevanju.
