Measurement of radioactivity in the environment - Air : radon-222 - Part 5 : continuous measurement method of the activity concentration

ISO 11665-5:2012 describes continuous measurement methods for radon-222. It gives indications for continuous measuring of the temporal variations of radon activity concentration in open or confined atmospheres.ISO 11665-5:2012 is intended for assessing temporal changes in radon activity concentration in the environment, in public buildings, in homes and in work places, as a function of influence quantities such as ventilation and/or meteorological conditions.

Le présent document donne des recommandations pour mesurer l'activité volumique du radon 222 dans l'atmosphère. Parmi les différentes méthodes existantes, seules les méthodes de mesure en continu sont couvertes par la présente norme. 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, de mars 1998.

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.
