Availability Notice


The MILDOS-AREA computer code is used to estimate the radiological impacts of airborne emissions from uranium mining and milling facilities. The code allows users to consider both conventional uranium ore operations and operations associated with in situ recovery facilities. The code is used by license applicants and U.S. Nuclear Regulatory Commission staff to perform routine radiological impact and compliance evaluations for various uranium recovery operations. As part of a major code update, the following improvements and additions were made to the code: (a) support for ores containing thorium-232 (Th-232) and its daughter radionuclides in addition to the currently supported uranium-238 (U-238) and its daughter radionuclides, (b) a revised area source model, (c) the capability to perform sensitivity analysis on specific input parameters, (d) the capability to use current meteorological data provided by the National Climatic Data Center, and (e) an interactive results module.
