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

Part 5: Continuous measurement method of the activity concentration

(ISO 11665-5:2012); German version EN ISO 11665-5:2015
Class/Status: Standard, valid
Released: 2015-11
VDE Art. No.: 0400164


This standard outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air. Part 5 of series ISO 11665 gives indications for continuous measuring the temporal variations of radon activity concentration in open or confined atmospheres.
