| Abstract: | Durante la Segunda Expedición Ecuatoriana a la Antártida, enmarcada en el proyecto de evaluación de radionucleídos en las Islas Shetland del Sur, se tomaron dos perfiles de suelo correspondientes a Bahía Almirantazgo, Isla Rey Jorge, y a Punta Fort Williams, Bahía Chile, Isla Greenwich. Las muestras fueron procesadas en la Universidad Austral de Chile. Los trabajos realizados en dichos perfiles son: Determinación de la concentración de Cs-137 y algunas características edáficas relevantes. Las muestras tomadas de un perfil practicado en Bahía Almirantazgo, se caracterizaron por una actividad superficial de Cs-137 considerablemente superior a la predicha para la banda latitudinal correspondiente. La penetración del Cs-137 es favorecida por la geomorfología y propiedades edáficas del lugar. Las muestras tomadas del perfil de Bahía Chile, presentan una actividad superficial de Cs-137 relativamente menor.
Two soil profiles corresponding to Almiralty Bay, King George Island; and Fort Williams Point, Chile Bay, Greenwich Islands; were obtained during the Second Ecuadorian Expedition to the Antarctica, as part of a research project dealing with the evaluation of radionucleides on South Shetland Islands. Samples were processed on Chilean Austral University.
Work performed on samples were: Determination of the concentration of Cs-137 and some outstanding edaphic characteristics. Samples from a profile on Almiralty Bay were characterized by a Cs-137 activity considerably higher to the predicted one for the corresponding latitudinal site. The penetration of Cs-137 is favored by the edaphic properties and by the geomorphology of the area. Samples from the profile on Chile Bay present a relatively minor surface Cs-137 activity. |
