Resumo
Certified reference materials are important tools for the quality assurance of analytical results. However there are several constraints for their widespread use in developing countries such as technological development or difficult access to imported goods. Another issue is that analyte level differences between imported certified reference materials and local laboratory samples may be a concern in the measurement process. This contribution describes the naturally occurring activity concentrations of 234U, 235U, 238U and 232Th, determined by Alpha Spectrometry after a radiochemical separation procedure and 40K and 210Pb determined by Gamma Ray Spectrometry in a Perna perna mussel reference material produced in Brazil. Obtained activity concentrations were included as information values in the certification process of the reference material.
