Measurement of radioactivity in the environment - Air: radon-222 Part 1: Origins of radon and its shortlived decay products and associated measurement methods
|Publication Date:||1 September 2015|
|ICS Code (Radiation measurements):||17.240|
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.
