Uranium which accumulates in process equipment and associated plumbing, ductwork, and filters is measured at Y-12 with portable NaI detectors using the Generalized Geometry Holdup (GGH) model. In this model all accumulations are modeled as points, lines, and areas. The width of point and line sources is also considered to account for detector response and the effects of self attenuation. The measurements
