ISO 11665-1:2012 PDF

Scope: This part of ISO 11665 outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air. a) spot measurement methods; b) continuous measurement methods; c) integrated measurement methods. This part of ISO 11665 provides several methods commonly used for measuring radon-222 and its short-lived decay products in air. This part of ISO 11665 also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts.
