Modelagem e Geometrização em PGNAA
O Prompt Gamma Neutron Analysis Activation (PGNAA) é uma das técnicas utilizadas atualmente na análise de materiais. Essa técnica define gráficos de intensidade espectral como função de energia (canais) para os elementos dentro de uma amostra. Esses gráficos (bibliotecas) permitem a determinação de …

In vivo nitrogen measurement by use of (n,2n) method and PGNAA
… and prompt gamma neutron activation analysis (PGNAA). The first method utilizes the fast neutron reaction 14 N(n,2n) 13N and the second uses the thermal reaction 14N(n,y)1 N. Both methods are currently in use at several different facilities for evaluation of the nutritional status of surgical …

In vivo detection of gadolinium by prompt gamma neutron activation analysis: An investigation of the potential toxicity of gadolinium-based contrast agents used in MRI
… by prompt gamma neutron activation analysis (PGNAA). PGNAA is a quantitative measurement technique that is completely non-invasive. Gadolinium has the highest thermal neutron capture cross section of all the stable elements. Gadolinium-based contrast agents are widely used in magnetic …

Development of a switchable radioisotope generator
… detection within canister and cask materials. PGNAA was simulated in MCNP with SNM and harmful chemicals using secondary neutrons from the SRG as another application study. The SRG was then proven to detect microstructure defects in cask and canister materials and positively identify SNM and …
