摘要：
We report a radiological study of a uranium mine located in Extremadura, in the south-west of Spain, in which mining work had ceased. One interest in the work is that the results can be used as a reference for the future evaluation of the effects produced by the restoration program. The radiological parameters selected to estimate the impact of the inactive mine were: Rn-222 in, air and water, Rn-222 exhalation, effective Ra-226 in soils and sediments, and natural uranium and Ra-226 in water. Chemical analyses of water samples and measurements of meteorological variables were also made. Average values of these radiological parameters are presented, We characterize the zone radiologically and estimate the influence of the mine on the basis of some of these parameters, while others are used to reflect the status of the installation, information which could be very useful in the near future when restoration is complete.
