DESCRIPTION
CSN EN ISO 11665-2
CSN EN ISO 11665-2 This part of ISO 11665 describes integrated measurement methods for short-lived radon-222 decay products[4]. 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. This part of ISO 11665 covers samples taken over periods varying from a few weeks to one year. This part of ISO 11665 is not applicable to systems with a maximum sampling duration of less than one week. The measurement method described is applicable to air samples with potential alpha energy concentration of short-lived radon-222 decay products greater than 10 nJ/m3 and lower than 1 000 nJ/m3.
