Evaluation of Cl in blood by NAA and XRF techniques: an alternative for pediatric practice. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 21-25, 2019, Santos, SP. <b>Proceedings...</b> Rio de Janeiro: Associação Brasileira de Energia Nuclear, 2019. p. 2825-2828.

The dosage of Cl in whole blood samples of twenty newborns were determined by Energy Disperse X-Ray Fluorescence (EDXRF) and the Instrumental Neutron Activation Analyses (INAA) analytical techniques. Particularly, the alternative methodology based on EDXRF technology, using a portable XRF spectrometer, showed to be a fast and efficient procedure for Cl dosage in whole blood. We intend to introduce benefits to clinical practice in children, especially newborns and premature infants using this alternative procedure.2825-2828openAccessbloodchlorineconcentration ratiogamma radiationhigh-purity ge detectorsneonatesneutron activation analysisoptimizationthermal neutronsx-ray fluorescence analysisTexto completo de eventohttps://orcid.org/0000-0001-7766-2692
