In this paper, the development of a neutron-activated concrete powder reference material is described. The material originated from core samples taken from a concrete bioshield of a decommissioned nuclear reactor which ceased operation almost 30 years ago after approximately 20 years of operation. The assigned values, which were in the Bq g(-1) range, for the radionuclides in the material were determined by a 'consensus' method from measurements made by 33 organisations from 15 countries.
