dc.description.abstractExpanded measurement uncertainty is an estimate characterizing the range of values at which the true value of a measurand is at a defined confidence level. Expanded uncertainty is one of the three pillars of metrology, along with metrological traceability and methodological validation. Due to the importance of this parameter, it was estimated following the Guide to the Expression of Uncertainty in Measurement (GUM) for element measurement results obtained by Instrumental Neutron Activation Analysis (INAA) performed with short irradiations at the Pneumatic System of the IEA-R1 research reactor at IPEN – CNEN/SP. Samples of Brazilian sardine (Sardinella brasiliensis), one of the most consumed species in the city of São Paulo were analyzed and Br, Cl, Mg, Mn, Na and K were determined. For the analyzed elements, the values of expanded uncertainty with coverage factor k = 2 are lower than natural variation (standard deviation) of the elements mass fractions observed in a collected batch of 10 individual specimens.pt_BR
