This document provides guidance for — the sampling process of the aerosol particles in the air using filter media. This document takes into account the specific behaviour of aerosol particles in ambient air (Annex B). — Two methods for sampling procedures with subsequent or simultaneous measurement: — the determination of the activity concentration of radionuclides bound to aerosol particles in the air knowing the activity deposited in the filter; — the operating use of continuous air monitoring devices used for real time measurement.
The activity concentration is expressed in becquerel per cubic metre (Bq？m-3 ). This document describes the test method to determine activity concentrations of radionuclides bound to aerosol particles after air sampling passing through a filter media designed to trap aerosol particles. The method can be used for any type of environmental study or monitoring.
