title: Certification of the reference material IRMM-426 for radionuclides in dried bilberries.
abstract: A new reference material for the activity concentration of (137)Cs, (40)K and (90)Sr in a dried berry matrix was certified from a batch of bilberries collected in the vicinity of the Chernobyl nuclear power plant. Radionuclides in this material were metabolised by the plants, therefore no spiking had to be performed. The material was processed at IRMM and homogeneity and stability of the certified parameters were demonstrated. The certified property values for (137)Cs, (40)K and (90)Sr were determined in the course of a supplementary comparison, CCRI(II)-S8.
