The determination of control level of uranium mining or milling contaminated cropland management using radiation protection optimization principle

An attempt was made to determine the control level of contaminated cropland management by using the principle of radiation protection optimization, and a series of integrated analytical and calculating methods were presented. The situation of the polluted cropland within a uranium mine was analyzed, and then the management objectives of radiation protection optimization were found out. In the end, the problems to be paid attention to in the process of polluted cropland management level determination were discussed, which provided a helpful reference for in-depth study of polluted cropland management standards.
