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

Part 3: Spot measurement method of the potential alpha energy concentration of its short-lived decay products

(ISO 11665-3:2020); German version EN ISO 11665-3:2020
Class/Status: Standard, valid
Released: 2020-08
VDE Art. No.: 0400399

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 3 of series ISO 11665 gives indications for spot measuring, after sampling at a given point for several minutes, the potential alpha energy concentration of short-lived radon-222 decay products in the air to make a rapid assessment and the conditions of use for the measuring devices.
