ABSTRACT
On the Romanian territory exploration, mining and milling of radioactive ore deposits, appeared for the first time 65 years ago in Bihor county. Thus in 1949 have been identified more deposits of uranium, some fully exploited (Baita, Avram Iancu) others insufficient known through research works carried out and was suspended. To achieve these objectives have been carried out, hundreds of miles of underground galleries and other works which resulted millions of tons of tailings stored in dozens of dumps, usually located in forested areas, on the banks of the mountain streams, hundreds of meters of underground or surface driling, thousands of square meters of unveiling ,etc., that changed the landscape of the region , partially affecting other environmental factors like water, soil, vegetation, fauna, etc. For diminution of environmental impact in the region, at the time of mine closing, were carried out several studies and programs for the restoration of the environment damaged by mining activities, but now some areas still require pecial attention. The present paper shows an assessment of areas affected by the exploitation of uranium ore deposit , 10 years after closing, taking into consideration the additional ecological restoration works.
