Radiation protection instrumentation - Radon and radon decay product measuring instruments - Part 2: Specific requirements for 222Rn and 220Rn measuring instruments
This part of IEC 61577 describes the specific requirements for instruments measuring the activity concentration of airborne 222Rn and 220Rn outdoors, in dwellings, and in workplaces including underground mines. This standard applies practically to all types of electronic measuring instruments that are based on either spot or continuous measurements. The activity concentration can be measured by pumping or by diffusing the air containing 222Rn and/or 220Rn into the sensitive volume of the detection unit or at a particular moment by taking an air sample (grab sampling).

Instrumentation pour la radioprotection - Instruments de mesure du radon et des descendants du radon - Partie 2: Exigences spécifiques pour les instruments de mesure du 222Rn et du 220Rn
L'IEC 61577-2:2014 décrit les exigences spécifiques relatives aux instruments destinés au mesurage de l'activité volumique des 222Rn et 220Rn en suspension dans l'air 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 de mesure électroniques utilisant des méthodes basées sur des prélèvements instantanés ou encontinu. Les différents types d'instrumentation utilisés pour les mesures sont indiqués par l'IEC 61577-1. Cette nouvelle édition inclut les modifications techniques significatives suivantes par rapport à l'édition précédente: - ajout de nouvelles exigences et de nouveaux essais concernant la performance; - harmonisation des exigences et des essais, concernant la performance, avec d'autres normes dans ce domaine.
Instrumenti za zaščito pred sevanjem - Instrumenti za merjenje radona in njegovih razpadnih produktov - 2. del: Posebne zahteve za instrumente za merjenje 222Rn in 220Rn
Ta del standarda IEC 61577 opisuje posebne zahteve za instrumente za merjenje koncentracije 222Rn in 220Rn v zraku na prostem, v stanovanjih in na delovnih mestih, vključno s podzemnimi rudniki.
Ta standard se uporablja za skoraj vse vrste elektronskih merilnih instrumentov, ki temeljijo na točkovnih ali neprekinjenih meritvah. Koncentracijo aktivnosti je mogoče izmeriti s črpanjem ali z razprševanjem zraka, ki vsebuje 222Rn in/ali 220Rn, v občutljivi detektor ali z odvzemom vzorca zraka v določenem trenutku (trenutno vzorčenje).
