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:
-
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.
