Measurement of radioactivity in the environment - Air: radon-222 - Part 6: Spot measurement methods of the activity concentration (ISO 11665-6:2020)

This document describes radon-222 spot measurement methods. It gives indications for carrying out spot measurements, at the scale of a few minutes at a given place, of the radon activity concentration in open and confined atmospheres.
This measurement method is intended for rapid assessment of the radon activity concentration in the air. The result cannot be extrapolated to an annual estimate of the radon activity concentration. This type of measurement is therefore not applicable for assessment of the annual exposure or for determining whether or not to mitigate citizen exposures to radon or radon decay products.
The measurement method described is applicable to air samples with radon activity concentration greater than 50 Bq·m−3.
NOTE    For example, using an appropriate device, the radon activity concentration can be spot measured in the soil and at the interface of a material with the atmosphere (see also ISO 11665-7[8]).

Ermittlung der Radioaktivität in der Umwelt - Luft: Radon-222 - Teil 6: Punktmessverfahren für die Aktivitätskonzentration (ISO 11665-6:2020)

Dieses Dokument beschreibt Punktmessverfahren für 222Rn. Er gibt Hinweise zur Durchführung einer Punktmessung der Radon-Aktivitätskonzentration innerhalb weniger Minuten an einem vorgegebenen Ort in offenen und umschlossenen Atmosphären.
Dieses Messverfahren wird verwendet für die schnelle Bestimmung der Radon-Aktivitätskonzentration in der Luft. Das Ergebnis kann nicht zur Prognose des Jahreswerts der Radon-Aktivitätskonzentration verwendet werden. Diese Art der Messung ist deshalb nicht anwendbar für die Bewertung der Ganzjahresexposition oder zur Bestimmung, ob die Belastung der Bevölkerung durch Radon oder Radon-Folgeprodukte verringert werden muss.
Das beschriebene Messverfahren ist auf Luftproben mit Radon-Aktivitätskonzentrationen von mehr als 50 Bq·m–3 anwendbar.
ANMERKUNG Bei Verwendung eines geeigneten Geräts kann die Radon-Aktivitätskonzentration beispielsweise im Erdboden und an der Grenzfläche zwischen einem Material und der Atmosphäre mittels Punktmessung bestimmt werden (siehe auch ISO 11665-7 [8]).

Mesurage de la radioactivité dans l'environnement - Air: radon 222 - Partie 6: Méthodes de mesure ponctuelle de l'activité volumique (ISO 11665-6:2020)

Le présent document décrit les méthodes de mesure ponctuelle du radon-222. Il donne des indications pour réaliser des mesures ponctuelles, à l'échelle de quelques minutes et en un point donné, de l'activité volumique du radon dans des atmosphères libres et confinées.
Cette méthode de mesure est destinée à une évaluation rapide de l'activité volumique du radon dans l'air. Le résultat ne peut pas être extrapolé à une estimation annuelle de l'activité volumique du radon. Par conséquent, ce type de mesurage ne s'applique pas à l'évaluation de l'exposition annuelle ni à la détermination de l'opportunité de réduire ou non l'exposition des citoyens au radon ou aux descendants du radon.
La méthode de mesure décrite s'applique à des échantillons d'air dont l'activité volumique du radon est supérieure à 50 Bq·m−3.
NOTE    À titre d'exemple, le mesurage ponctuel de l'activité volumique du radon dans le sol et au niveau de l'interface entre un matériau et l'atmosphère peut être réalisé en utilisant un dispositif approprié (voir également ISO 11665-7[8]).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
