AbstractAbstract
[en] Sistematic radiation intensity measurements were alone at Morro do Ferro hill in the Pocos de Caldas Alkaline Complex, using portable Scintrex spectrometer for U, Th, K and total counting (TC). Complementary geochemical analyses were alone on selected 26 samples. It was observed that there are many radiation focii in that place and they are oriented in the E-W direction. The geochemical analyses show that Uranium has participated also in the inicial mineralization of radioactive elements. The contribution of 238U series daugher elements is relatively strong although Uranium was 'washed' by leaching. (Author)

Medidas sistematicas da intensidade de radiacao foram realizadas na colina do Morro do Ferro no complexo alcalino de Pocos de Caldas, usando um espectrometro Scintrex portatil para U, Th, K e contagem total (CT). Analises geoquimicas complementares foram feitas em 26 amostras selecionadas. Foi observado que existem muitos focos de radiacao naquele local e eles estao orientados na direcao L-O. As analises geoquimicas mostraram que o uranio participou tambem da mineralizacao inicial dos elementos radioativos. A contribuicao da serie 238U de elementos filhos e relativamente forte embora o uranio tenha sido lixiviado. (L.H.L.L.)Original Title
