Comparative studies regarding the impact on environmental factors of the uranium mining activity in some areas from Romania

摘要

Studies concerning levigation and migration processes of uranium and radium from ore dumps, possibilities of environmental contamination of some areas related to the exploitations and explorations (Banat, Oriental Carpathians, Apuseni Mountains) as well as the pollution sources recognifiton and their delimitation an maps, are presented in this paper. A lot of indirect factors which may influence the pollution degree are studied, such as: water pH, water flow, valley slope and form, altitude and vegetation presence on the dumps. Comparative studies of irradiation and pollution processes from uranium exploration and exploitation mining areas are also presented.
