A radioactive waste screening system comprising at least one subsystem, at least one computer assembly operatively associated with and configured to receive measurement data from the at least one subsystem, and control logic in communication with the at least one computer assembly. The at least one subsystem is selected from the group consisting of a packaged waste screening subsystem, a volume waste screening subsystem, a subsurface waste characterization subsystem, and a surface waste characterization subsystem. The control logic is configured to verify the operability of the at least one subsystem, to control the at least one subsystem, and to assess the radioactivity of at least one material at least partially based on the measurement data received by the at least one computer assembly. A method of assessing a potentially radioactive material, and a method of determining the radioactivity of a material are also described.
