Measurement of radioactivity in the environment - Air : radon-222 - Part 1 : origins of radon and its short-lived decay products and associated measurement methods

ISO 11665-1:2012 outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air. The measurement methods fall into three categories:spot measurement methods;continuous measurement methods;integrated measurement methods.ISO 11665-1:2012 provides several methods commonly used for measuring radon-222 and its short-lived decay products in air.ISO 11665-1:2012 also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts.

Measurement of radioactivity in the environment - Air : radon-222 - Part 1 : origins of radon and its short-lived decay products and associated measurement methods

ISO 11665-1:2012 outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air.

The measurement methods fall into three categories:

  1. spot measurement methods;
  2. continuous measurement methods;
  3. integrated measurement methods.

ISO 11665-1:2012 provides several methods commonly used for measuring radon-222 and its short-lived decay products in air.

ISO 11665-1:2012 also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts.

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!
