Certification of cobalt in a nickel metal reference material for neutron dosimetry IRMM-521R

Funded under: FP7-JRC

Abstract

This certification report describes the processing and characterisation of IRMM-521R, a certified reference material (CRM) consisting of nickel metal foil for neutron dosimetry applications. To avoid spectral interference due to cobalt impurities, IRMM-521R has a certified upper limit of cobalt content, thus reducing the uncertainty of dosimetry measurements. IRMM-521R consists of a high purity nickel foil with a cobalt content of < 0.26 mg/kg. With a 95 % probability, the cobalt content of samples of IRMM-521R is below this level.
