dc.description.abstract | El cáncer de cuello uterino tiende a ocurrir en la mediana edad y se diagnostica con mayor frecuencia en mujeres de entre 37 y 59 años. Rara vez se desarrolla en mujeres menores de 20 años. Muchas mujeres mayores no se dan cuenta de que el riesgo de cáncer de cuello uterino sigue existiendo a medida que envejecen . El uso de radiaciones ionizantes para el tratamiento del cáncer de cuello uterino conlleva un riesgo inherente debido a los efectos nocivos que puede generar en el organismo o tejidos vivos. Es por ello que en este trabajo se cuantifica el grado de contaminación inducida por el isótopo radiactivo Ir-192, en tratamientos intracavitarios del cáncer de cuello uterino, con una alta tasa de dosis de radiación. Aquí se determina la distribución de oligoelementos y sus concentraciones en un grupo de muestras de sangre de pacientes. Para ello se utiliza la técnica de Espectroscopía de Fluorescencia de Rayos X de Reflexión Total (TXRF), que es una técnica analítica multielemental que permite la determinación de oligoelementos en muestras líquidas. Los resultados en todas las muestras post-irradiadas tienen una mayor concentración de K, Ca y Fe que las normales. Además, en ellos se encontraron nuevos elementos altamente contaminantes, en concentraciones significativas, en comparación con las normales. | |
dc.description.abstract | Cervical cancer tends to occur in middle age and is most often diagnosed in women between 37 and 59 years old. It rarely develops in women under 20 years of age. Many older women do not realize that the risk of cervical cancer continues as they age. The use of ionizing radiation for the treatment of cervical cancer carries an inherent risk due to the harmful effects it can have on the body or living tissues. That is why in this work the degree of contamination induced by the radioactive isotope Ir-192 is quantified, in intracavitary treatments for cervical cancer, with a high radiation dose rate. Here the distribution of trace elements and their concentrations in a group of blood samples from patients is determined. For this, the Total Reflection X-ray Fluorescence Spectroscopy (TXRF) technique is used, which is a multi-element analytical technique that allows the determination of trace elements in liquid samples. The results in all post-irradiated samples have a higher concentration of K, Ca and Fe than normal. In addition, new highly polluting elements were found in them, in significant concentrations, compared to normal ones. | eng |
