Measurement of radioactivity in the environment – Air: radon-222

Part 7: Accumulation method for estimating surface exhalation rate

(ISO 11665-7:2012)
Class/Status: Standard, withdrawn

VDE Art. No.: 0493047


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.
