Influencia de la precipitación en la concentración de radón en el subsuelo y su efecto en la exhalación de este hacia la atmósfera (ejemplos de tres zonas de Costa Rica). Tópicos Meteorológicos y Oceanográficos, 10(2), 57-62.https://daki.cigefi.ucr.ac.cr/handle/123456789/168Measurements of concentration of radon were made in the subsoil in three sites of Costa Rica: San José, Alajuela and Guanacaste. The influence of the precipitation studies on the concentration of radon and an analysis of the exhalation is made of this towards the atmosphere, based on the equations of tranport of this gas through porous means. Only the difusiva component of the exhalation is taken in consideration. One of the places presents/displays an important flow, probably due to its proximity with a volcano.esArticle
