Abstract

The invention discloses a technology for treating radon and radon progeny uranium mining and metallurgy airborne radioactive pollution through moss artificial surface crusting. The technology comprises the steps that one, radon and radon progeny enriched moss plants are selected; two, moss surface crusting germplasm is prepared; three, moss artificial surface crusting planting is conducted; four,moss artificial biological surface crusting caring is conducted. According to the technology, the uranium mining and metallurgy airborne radioactive pollution of radon and radon progeny and the like is treated through the moss artificial surface crusting, the technology is advanced, the implementation of a method is easy, the operation is convenient, the cost is low, and novel technological approaches are provided for the environmental treatment of the airborne radioactive pollution of uranium tailing, uranium wasted stone field, uranium mountain retirement regions and the like.

Description

technical field [0001] The invention relates to the field of airborne radioactive pollution treatment of radon and daughter uranium mining and milling, in particular to a method for treating airborne radioactive pollution of radon and daughter uranium mining and milling. It is suitable for comprehensive treatment of airborne radioactive pollution environments such as uranium tailings, uranium waste rock sites and decommissioned areas of uranium mines. Background technique [0002] With the rapid development of the world economy, environmental protection and the continuous depletion of fossil energy, the development and utilization of large-scale nuclear energy has become an inevitable choice. The development of nuclear energy inevitably requires the stable and lasting development of the uranium mining and metallurgy industry. Global 7.0×10 7 U around kg / year 3 o 8 Basically, they are produced by uranium mining and metallurgy. With the development of uranium mining and m...
