This document describes integrated measurement methods for short-lived radonâ??222 decay products[ 4]. It gives indications for measuring the average potential alpha energy concentration of shortâ??lived radon-222 decay products in the air and the conditions of use for the measuring devices.This document covers samples taken over periods varying from a few weeks to one year. This document 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 10ÂnJ/m3 and lower thanÂ1Â000ÂnJ/m3. NOTE For informative purposes only, this document also addresses the case of radon-220 decay products, given the similarity in behaviour of the radon isotopes 222 and 220.
