It is important to monitor the amount of nuclear material that is held up in facilities for safeguards, criticality, waste management, worker safety, and facility operations purposes.  Measurements of holdup require rugged detector systems and a technique that can determine both the isotopic distribution and mass of the special nuclear material (SNM) despite various geometries, material properties, shielding materials, and contaminants.  The current methods of measuring holdup could be improved upon with an update in equipment, software, and technique.  The current practices for measuring holdup are reviewed, followed by the existing difficulties in holdup measurements, and then a sampling of newer technologies and techniques that could be useful to this field.
