Measurement of radioactivity in the environment. Air: radon-222. Origins of radon and its short-lived decay products and associated measurement methods | Status: Superseded, Withdrawn

1 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. The measurement methods fall into three categories:

1. a) spot measurement methods;
2. b) continuous measurement methods;
3. 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.
