Contents

This International Standard outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air. This part of ISO 11665 series gives guidance for determination of the Radon-222 suface exhalation rate during a short span of time (a few hours) at a specified place.

This Standard is withdrawn and is replaced by the following
