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-222 activity concentration in open and confined atmospheres.
