Occurrence and migration of uranium in groundwater system.

Uranium is an important strategic resource of the country, which is of great significance to national economy and national defense security. The chemical toxicity and radioactivity of uranium can cause long-term, sustained and irreversible harm to human and environment, the point-to-surface pollution caused by the migration of uranium in the environment and groundwater system has attracted extensive attention. Many scholars have studied the sources of uranium, the forms of uranium in groundwater system, the enrichment and migration of uranium and the treatment of uranium pollution, and used models and related software to evaluate and predict the impact of the migration of radionuclide uranium on human and environment. This paper will provide a more comprehensive theoretical basis for the mechanism of uranium contamination. [ABSTRACT FROM AUTHOR]
