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

Part 5: Continuous measurement methods of the activity concentration

(ISO 11665-5:2020); German version EN ISO 11665-5:2020
Class/Status: Standard, valid
Released: 2020-08
VDE Art. No.: 0400400

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-222 activity concentration in open or confined atmospheres.
