ISO 11665-2:2012 describes integrated measurement methods for short-lived radon-222 decay products. It gives indications for measuring the average potential alpha energy concentration of short-lived radon-222 decay products in the air and the conditions of use for the measuring devices.
ISO 11665-2:2012 covers samples taken over periods varying from a few weeks to one year. ISO 11665-2:2012 is not applicable to systems with a maximum sampling duration of less than one week.
