dc.description.abstractA los isótopos radiactivos $^{232}$Th, $^{238}$U y $^{40}$K se les conoce por sus siglas en inglés como NORM (Normally Occurring Radioactive Materials). Se tomaron 25 muestras de agua en la zona de estudio, el Valle del Magdalena Medio, de donde se determinaron las concentraciones de estos radionúcleos usando un sistema de espectroscopía gamma de alta resolución. Determinando el umbral de decisión y límite de detección se encontró que 7 muestras tienen presencia de $^{238}$U, 2 muestras contienen $^{40}$K pero estos niveles de uranio y potasio están por debajo del límite de detección. Adicionalmente, se reporta que ninguna de las muestras tiene concentración de actividad de torio superior al límite de decisión. (Texto tomado de la fuente)
dc.description.abstractThe radioactive isotopes $^{232}$Th, $^{238}$U y $^{40}$K are known as NORM (Normally Occurring Radioactive Materials). Taking a series of water samples in the study zone, the Middle Magdalena Valley, the concentration of these radionuclides is determined using a high-resolution gamma spectroscopy system. Determining the decision threshold and detection limit, it was found that 7 samples had the presence of $^{238}$U, 2 samples contained $^{40}$K but these uranium and potassium levels are below the detection limit. Additionally, it is reported that none of the samples has a thorium activity concentration above the decision limit.
