title: Remarks on representative ground-level air monitoring.
abstract: The methods applied and the typical influences affecting representative measurements of radionuclides contained in ground-level aerosols are summarized. The activity concentrations of (7)Be, (22)Na, (40)K, (137)Cs, and (210)Pb were determined in weekly collected samples and the ratio "sample A/sample B" was calculated over a period of 5 years. The results are compared with findings from literature. The estimation of the limits of comparability and reliability were extended to (22)Na, (40)K, (137)Cs, and (210)Pb measurements.
