“…Gamma spectrum evaluation and quantitative analysis of each sample and control were done by k 0 -IAEA software based on k 0 -method [27] (single comparator method) and multipurpose c-ray spectrum analysis software; WinSPAN-2010 version 2.10 which works on the basis relative comparator methodology. An Al-Au wire monitor (99.9 % Al-0.1 %Au) was used as both reactor thermal flux monitor and single comparator element in the case of k 0 -method, while standard reference materials were use concurrently as comparator reference standard and control.…”

The present investigation was undertaken to determine the nutritional compositions (mineral elements) of three green leafy vegetable; Dandelion (Taraxacum Officinale), Ayoyo (Corchorus Olitorius) and Baobab (Adasonia Digitata). The ultimate goal is to improve nutrition and health by advocating for increased consumption of indigenous green leafy vegetables with an objective to increasing public acceptance, awareness and utilization. The mineral elements were determined using instrumental neutron activation analysis, over 20 elements were detected. However, 14 mineral elements were quantitatively evaluated on the basis of k 0 -method and relative comparator method. The leaves were characterized with high concentration of Mg, Ca, Cl and K, and substantive amount of Mn, Fe, Zn, Cu and I. The composition of the mineral elements and its respective percent contribution to Recommended Dietary Allowance/Adequate Intake (RDA/ AI) for various life groups indicates that reasonable consumption of any of the three green leafy vegetable can contribute substantive amount of daily nutritional requirement for minor nutrients like; I, Cu, Zn, Mn, and Fe as well as major nutritional (Mg, Ca, Cl and K) needs for all life groups. Each of the leaves was also characterize with high K/Na ratios. Tolerable upper intake levels (UL) analysis also showed no significant abuse for the mineral elements determined. Other potential toxic elements (As, Cd and Hg) and non-nutritional minerals (Br, V, Al and Ba) were either not detected or were found in low concentrations.

In(n,) 114m In, 186 W(n,) 187 W E 191 Ir(n,) 192 Ir Lívia Fernandes Barros RESUMO Este trabalho teve o intuito de contribuir para a melhoria na qualidade dos valores de k0 e Q0 para as reações 74 Se(n,) 75 Se, 113 In(n,) 114m In, 186 W(n,) 187 W e 191 Ir(n,) 192 Ir. As medições das amostras irradiadas no reator IEA-R1 e das fontes padrão da Agência Internacional de Energia Atômica (IAEA) foram realizadas por espectrometria gama de alta resolução em detector de HPGe. A fim de investigar melhor as eficiências nos intervalos de energia onde não havia pontos experimentais, foi aplicado o Método de Monte Carlo. As contribuições originais deste trabalho foram: a análise de covariância associada ao Método dos Mínimos Quadrados, que foi utilizada para o tratamento adequado das incertezas para as reações 74 Se(n,) 75 Se, 113 In(n,) 114m In, 186 W(n,) 187 W e 191 Ir(n,) 192 Ir estudadas neste trabalho, onde todas as incertezas parciais envolvidas no processo foram utilizadas; a determinação experimental dos fatores de auto-blindagem para nêutrons térmicos (Gth) e epitérmicos (Ge) utilizados nas determinações de k0 e Q0 para a reação 113 In(n,) 114m In e na determinação experimental do fator de autoblindagem para nêutrons epitérmicos (Ge) utilizado na determinação de k0 e Q0 para a reação 186 W(n,) 187 W, que não foram observadas na literatura, além da determinação de k0 obtida para a reação 186 W(n,) 187 W na energia de 625,51 keV, que também não existe na literatura recomendada. Os valores de k0 e Q0 obtidos para todas as reações foram comparados aos valores encontrados na literatura.
