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

Part 6: Spot measurement method of the activity concentration

(ISO 11665-6:2012); German version EN ISO 11665-6:2015
Class/Status: Standard, valid
Released: 2015-11
VDE Art. No.: 0400165


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 6 of series ISO 11665 gives indications for spot measuring, at the scale of a few minutes at a given point, the radon activity concentration in open and confined atmospheres.
