Measurement of radioactivity in the environment - Air: radon-222 - Part 2: Integrated measurement method for determining average potential alpha energy concentration of its short-lived decay products (ISO 11665-2:2019)
This document describes integrated measurement methods for short-lived radon‑222 decay products[4]. It gives indications for measuring the average potential alpha energy concentration of short‑lived radon-222 decay products in the air and the conditions of use for the measuring devices.
This document covers samples taken over periods varying from a few weeks to one year. This document is not applicable to systems with a maximum sampling duration of less than one week.
The measurement method described is applicable to air samples with potential alpha energy concentration of short-lived radon-222 decay products greater than 10 nJ/m3 and lower than 1 000 nJ/m3.
NOTE For informative purposes only, this document also addresses the case of radon-220 decay products, given the similarity in behaviour of the radon isotopes 222 and 220.

Dieses Dokument beschreibt integrierende Messverfahren für kurzlebige 222Rn-Folgeprodukte [4]. Es gibt Hinweise für die Bestimmung des Durchschnittswerts der potenziellen Alpha-Energiekonzentration der kurz-lebigen 222Rn-Folgeprodukte in der Luft und für die Bedingungen zum Einsatz der Messgeräte.
Dieses Dokument beinhaltet die Probenahme während Zeiträumen, die von wenigen Wochen bis zu einem Jahr variieren. Dieses Dokument ist nicht anwendbar auf Messsysteme mit einer maximalen Dauer der Pro-benahme von weniger als einer Woche.
Das hier beschriebene Messverfahren ist anwendbar für Luftproben mit einer potenziellen Alpha-Energiekon-zentration der kurzlebigen 222Rn-Folgeprodukte von über 10 nJ m–3 und unter 1 000 nJ m–3.
ANMERKUNG Zur Information behandelt dieses Dokument auch den Fall von 220Rn-Folgeprodukten und zeigt die Ähnlichkeit im Verhalten der Radonisotope 222 und 220.

Le présent document décrit les méthodes de mesure intégrée pour les descendants à vie courte du radon 222[4]. Elle donne des indications pour mesurer l'énergie alpha potentielle volumique moyenne des descendants à vie courte du radon 222 dans l'air et sur les conditions d'utilisation des dispositifs de mesure.
Le présent document concerne des échantillons prélevés sur des périodes allant de quelques semaines à un an. Le présent document ne s'applique pas aux systèmes dont la durée de prélèvement maximale est inférieure à une semaine.
La méthode de mesure décrite s'applique aux échantillons d'air ayant une énergie alpha potentielle volumique des descendants à vie courte du radon 222 supérieure à 10 nJ/m3 et inférieure 1 000 nJ/m3.
NOTE À titre informatif uniquement, le présent document traite également le cas des descendants du radon 220 en raison de la similitude de comportement des isotopes 222 et 220 du radon.

Ta dokument opisuje integrirane merilne metode za kratkožive razpadne produkte radona-222[4]. Podaja navedbe za merjenje povprečne potencialne koncentracije alfa energije kratkoživih razpadnih produktov radona-222 v zraku in pogoje uporabe za merilne naprave. Ta dokument obravnava vzorce, odvzete v obdobjih vse od nekaj tednov do enega leta. Ta dokument se ne uporablja za sisteme z najdaljšim obdobjem vzorčenja manj kot en teden. Opisana merilna metoda se uporablja za vzorce zraka s potencialno koncentracijo alfa energije kratkoživih razpadni produktov radona-222, ki so večji od 10 nJ/m3 in manjši od 1000 nJ/m3.
