| Resumen : | El trabajo de titulación que a continuación se presenta consiste en la detección y cuantificación de los niveles de concentración del gas radiactivo de origen natural radón Rn222, así como la determinación de puntos críticos y estimación de dosis efectiva absorbida por guías dentro de la caverna Jumandy perteneciente a la comunidad Kichwa Ruku Jumandy Kawsay ubicada en el cantón de Archidona, provincia de Napo en Ecuador... |
| Descripción : | The graduation work presented as follows consists of the detection and quantification of the concentration levels of radioactive gas radon222 of natural origin, as well as the determination of the critical points and the estimate of the effective dose absorbed by the guides inside the Jumandy cavern belonging to the Kichwa Ruku Jumandy Kawsay community, in the canton of Archidona, province of Napo, in Ecuador. This area is located according to the feasibility map of uranium of Ecuador, in one of the top-priority areas for obtaining uranium. The measurement methodology was carried out during the months of July, August, September and October of 2017, in three different monitoring points inside the cavern. The measuring equipment used was of active and continuous method, where, through a diffusion chamber, the radon222 gas was detected and quantified. It is important to note that a mineralogical characterization of 4 cavern samples was carried out in order to determine whether these minerals contained radioactive materials of natural origin. The average levels of concentration obtained in the three points, in a period of 4 months within the Jumandy cavern, exceeded the maximum permissible limit of 4 pCi L 148 Bq m3 recommended by international standards, as well as the estimate of the effective dose absorbed by the guides that spend their work hours inside the caverns, which also exceed the maximum permissible levels of 1 mSv year for the personnel not occupationally exposed, recommended by the International Atomic Energy Agency. As a final part of this thesis, a mitigation proposal was prepared, which consist of modifying the work hours in which the guides were exposed to higher concentrations of radon222 in order to reduce the estimated effective dose absorbed. |
