Geohydrologic, geochemical, and geologic controls on the occurrence of radon in ground water near Conifer, Colorado, USA

Radon concentrations in ground and drinking water in the state of Chihuahua, Mexico

“…This is explained by the fact that water does not flow from a point, but from a great volume surrounding the well. Lawrence et al (1991) have reported a strong inverse relationship between the dissolved radon content in water and transmissibility of water in the aquifer. In their case, fractured rocks compose the aquifer.…”

Radon concentration in drinking water in villages nearby Rafsanjan fault and evaluation the annual effective dose

“…The highest concentration of radon in granite aquifer is measured [6,9]. The presence of 238 U, in granite and its decay produce 234 Th and 226 Ra 226 Ra is causing radon gas that is alpha particle emitter [22].Radon concentration is dependent on the position of the geochemical and geological phenomena such as the presence of faults and folded layers [23]. Due to the likely presence of radon in water supplies near fault, radon measurements were studied in ''Rafsanjan fault''.…”

Estudio experimental del tiempo de disolución del Rn-222 en agua y algunas implicaciones en la geología

“…En muchos casos el agua del acuífero recorre distancias del orden de metros antes de llegar a la naciente. Si la velocidad de circulación de esta permite que el radón transportado por ella, en disolución, no se desintegre por completo antes de llegar a la naciente, entonces se podrá encontrar una cantidad importante de radón en este lugar (Andrews & Lee, 1979;Lawrence et al, 1991). De aquí que los acuíferos deban ser considerados sitios de interés a la hora de efectuar mediciones de la concentración de radón, pues estos pueden llevar más rápidamente la señal geoquímica a la superficie, donde generalmente se instalan los equipos de medición.…”
