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 lack of 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 presents the 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. The activity concentrations obtained were included as
information values in the certification process of the reference material.
