Abstract

A new reference material for the activity concentration of ¹³⁷Cs, ⁴⁰K and ⁹⁰Sr 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 ¹³⁷Cs, ⁴⁰K and ⁹⁰Sr were determined in the course of a supplementary comparison, CCRI(II)-S8.
