The results provide a radiolocation through 500 m. of limestone and wet shale, and a radioconection through 890 m. of karstified limestones. Giving the relation between the electrical conductivity of the rock and the attenuation of the signal, the results suggest that the device could be used as a geophysical tool}, publisher = {Sociedad Geológica de España}, title = {Prueba de Radiolocalización y Radioenlace entre Candanchú y el Túnel Ferroviario Internacional de Canfránc (Huesca)}, title = {Radiolocation and radioconnection at the international railway tunnel of Canfranc (Huesca)}, author = {Ayuso, N. and Cuchí Oterino, José Antonio and Villarroel Salcedo, J.
