Measurement of radioactivity in the environment - Air : radon-222 - Part 4 : integrated measurement method for determining average activity concentration using passive sampling and delayed analysis

ISO 11665-4:2012 describes radon-222 integrated measurement techniques with passive sampling. It gives indications for determining the average activity concentration of the radon-222 in the air from measurements based on easy-to-use and low-cost passive sampling, and the conditions of use for the sensors. ISO 11665-4:2012 covers samples taken without interruption over periods varying from a few days to one year.

Nuclear energy - Measurement of radioactivity in the enviromment - Air - Radon 222 : methods for integrated measurement of the average volumic activity of radon in the atmospheric environment, with a passive collection and an deferred analysis

Le présent document donne des recommandations pour mesurer l'activité volumique moyenne du radon 222 par prélèvement passif dans l'atmosphère et analyse en différé. Parmi les différentes méthodes existantes, seules les méthodes de mesure intégrée sont couvertes par le présent document. Ce document décrit le mode de prélèvement, le mode de détection et les conditions d'utilisation. Il doit être utilisé conjointement avec la norme NF M 60-763.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
