Abstract

The invention discloses a technology for controlling radon and radon progeny uranium mining and metallurgy airborne radiation contaminations through artificial algae crusts. The technology comprises the following steps that first, radon and radon progenies are selected to enrich algae; secondly, algae crust breeding germplasms are prepared; thirdly, the artificial biological algae crusts are planted; fourthly, the artificial biological algae crusts are maintained. The technology for controlling the radon and radon progeny uranium mining and metallurgy airborne radiation contaminations throughthe artificial algae crusts is advanced, the method is easy to implement, the operation is convenient, the cost is low, and a new technological approach is provided for controlling the airborne radiation contaminated environments in a uranium tailings area, a uranium waste-rock yard, a uranium mine close-down area and the like.

Description

technical field [0001] The invention relates to the technical field of radioactive pollution control, in particular to a method for treating radon and daughter uranium mining and smelting airborne radioactive pollution by algae artificial crust. 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 metallurgy, a large number ...
