Report Title:Intercomparison of Radionuclides in Environmental Samples 2000-2001
Activity Acronym:BOK-1
Authors:C. L. Fogh, S. P. Nielsen, M. J. Keith-Roach
Abstract:An intercomparison exercise on radionuclides in environmental samples was carried out during 2000-2001 as part of a Nordic NKS project. The exercise included six sample types (aerosols, dry milk, soil, seawater, seaweed and lake water) and a range of man-made and naturally occurring radionuclides, mainly gamma-emitters but also beta- and alpha-emitters. A total of 25 Nordic and Baltic laboratories participated. The analytical quality across participants was generally good with about two thirds of the results in close agreement with estimated mean values. The exercise has demonstrated improved agreement between the results and more realistic analytical uncertainties submitted by the participants compared with a previous exercise carried out during 1998-1999 in the same NKS project.
