This document 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 document provides several methods commonly used for measuring radon-222 and its short-lived decay products in air.
This document also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts
