BS EN ISO 11665-1:2019

This standard BS EN ISO 11665-1:2019 Measurement of radioactivity in the environment. Air: radon-222 is classified in these ICS categories:

• 17.240 Radiation measurements
• 13.040.01 Air quality in general

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:

1. spot measurement methods;

2. continuous measurement methods;

3. 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.
