Measurement of radioactivity in the environment - Air: radon-222 - Part 11: Test method for soil gas with sampling at depth (ISO 11665-11:2016)

ISO 11665-11:2016 describes radon-222 test methods for soil gas using passive and active in-situ sampling at depth comprised between surface and 2 m.
ISO 11665-11:2016 gives general requirements for the sampling techniques, either passive or active and grab or continuous, for in-situ radon-222 activity concentrations measurement in soil gas.
The radon-222 activity concentration in the soil can be measured by spot or continuous measurement methods (see ISO 11665‑1). In case of spot measurement methods (ISO 11665‑6), the soil gas sampling is active only. On the other hand, the continuous methods (ISO 11665‑5) are typically associated with passive soil gas sampling.
The measurement methods are applicable to all types of soil and are determined according to the end use of the measurement results (phenomenological observation, definition or verification of mitigation techniques, etc.) taking into account the expected level of the radon-222 activity concentration.
These measurement methods are applicable to soil gas samples with radon activity concentrations greater than 100 Bq/m3.
NOTE          This part of ISO 11665 is complementary with ISO 11665‑7 for characterization of the radon soil potential.

Ermittlung der Radioaktivität in der Umwelt - Luft: Radon-222 - Teil 11: Verfahren zur Probenahme und Prüfung von Bodenluft (ISO 11665-11:2016)

Dieser Teil von ISO 11665 beschreibt Prüfverfahren für Radon-222 in der Bodenluft mittels passiver und akti-ver In-situ-Probenahme in Tiefen im Bereich zwischen der Erdoberfläche und 2 m.
Dieser Teil von ISO 11665 enthält allgemeine Anforderungen an die Probenahmetechniken, die entweder passiv oder aktiv sind und kurzzeitig oder kontinuierlich für die In-situ-Messung der Radon-222-Aktivitätskon-zentration in der Bodenluft erfolgen.
Die Radon-222-Aktivitätskonzentration im Erdboden kann durch Punktmessung oder kontinuierliche Mess-verfahren ermittelt werden (siehe ISO 11665-1). Im Falle von Punktmessungen (ISO 11665-6) sind die Pro-benahmen der Bodenluft aktiv. Im Gegensatz dazu beruhen die kontinuierlichen Verfahren (ISO 11665-5) in der Regel auf passiven Probenahmen.
Die Messverfahren sind anwendbar auf alle Bodentypen und sind durch die Verwendung der Messergebnisse bei Berücksichtigung des zu erwartenden Wertes der Radon-222-Aktivitätskonzentration festgelegt (phäno-menologische Beobachtung, Festlegung und Verifikation von Reduzierungsmaßnahmen usw.).
Diese Messverfahren sind anwendbar auf Bodenluftproben mit Radon-Aktivitätskonzentrationen größer als 100 Bq·m–3.
ANMERKUNG Dieser Teil von ISO 11665 ergänzt ISO 11665-7 hinsichtlich der Charakterisierung des Radonpotenzials im Erdboden.

Mesurage de la radioactivité dans l'environnement - Air: radon 222 - Partie 11: Méthode d'essai pour le gaz du sol avec un prélèvement en profondeur (ISO 11665-11:2016)

L'ISO 11665-11:2016 décrit les méthodes d'essai permettant de mesurer le radon 222 dans le gaz du sol avec un prélèvement in situ passif ou actif à une profondeur comprise entre la surface et 2 m.
L'ISO 11665-11:2016 spécifie les exigences générales relatives aux techniques de prélèvement, passif ou actif et ponctuel ou en continu, en vue du mesurage in situ de l'activité volumique du radon 222 dans le gaz du sol.
L'activité volumique du radon 222 dans le sol peut être mesurée par des méthodes de mesure ponctuelle ou en continu (voir l'ISO 11665‑1). Dans le cas des méthodes de mesure ponctuelle (ISO 11665‑6), le prélèvement de gaz du sol est uniquement actif. En revanche, les méthodes en continu (ISO 11665‑5) sont généralement associées à un prélèvement passif du gaz du sol.
Les méthodes de mesure s'appliquent à tous les types de sol et sont déterminées selon l'objectif final des résultats de mesure (observation phénoménologique, détermination ou vérification de techniques d'atténuation, etc.) en tenant compte du niveau attendu de l'activité volumique du radon 222.
Ces méthodes de mesure s'appliquent aux échantillons de gaz du sol ayant des valeurs d'activité volumique du radon supérieures à 100 Bq/m3.
NOTE          L'ISO 11665-11:2016 est complémentaire à l'ISO 11665‑7 pour la caractérisation du potentiel radon des sols.

Merjenje radioaktivnosti v okolju - Zrak: radon Rn-222 - 11. del: Preskusna metoda za vzorčenje plinov iz tal (ISO 11665-11:2016)

Standard ISO 11665-11:2016 opisuje preskusne metode za določanje radona-222 v plinih iz tal s pasivnim in aktivnim vzorčenjem na kraju samem med površino in globino 2 m.
Standard ISO 11665-11:2016 določa splošne zahteve za tehnike vzorčenja, pasivno ali aktivno in zajemno ali neprekinjeno, za merjenje koncentracij aktivnosti radona-222 na kraju samem v plinih iz tal.
Koncentracije aktivnosti radona-222 v tleh je mogoče meriti s točkovnimi ali neprekinjenimi metodami merjenja (glej standard ISO 11665-1). Pri metodah točkovnega merjenja (ISO 11665‑6) je aktivno samo vzorčenje plinov iz tal. Po drugi strani so neprekinjene metode (ISO 11665‑5) tipično povezane s pasivnim vzorčenjem plinov iz tal.
Metode merjenja se uporabljajo za vse vrste tal in so določene glede na končno uporabo rezultatov meritev (fenomenološko opazovanje, definicija ali preverjanje tehnik ublažitve ipd.) ob upoštevanju pričakovane ravni koncentracije aktivnosti radona-222.
Te metode merjenja se uporabljajo za vzorce plinov iz tal s koncentracijami aktivnosti radona, večjimi od 100 Bq/m3.
OPOMBA: Ta del standarda ISO 11665 dopolnjuje standard ISO 11665‑7 za karakterizacijo potenciala za radon v tleh.

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

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.
