SC 2-9: Radiation Safety Program Concerns Transitioning from Operating Facility to Decommissioning Phase


  • The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) provides extensive guidance for the design and implementation of scoping, characterization and final status surveys (FSS). The guidance document is comprehensive and includes guidance for instrumentation selection/use, waste management, survey planning/statistical considerations and quality assurance. An update (revision 2) of MARSSIM is expected in 2022/2023.
  • Abelquist’s handbook for MARSSIM users, “Decommissioning Health Physics”, provides excellent guidance regarding interface with regulatory agencies, release criteria, exposure pathways, design of the FSS, etc.
  • NUREG-1757, Consolidated Decommissioning Guidance.
  • The 1999 Health Physics Society Summer School addressed the field of decommissioning and restoration of nuclear facilities. The proceedings have been compiled (available) and include a wide range of topics, such as an overview of NRC, State, IAEA and DOE perspectives on decommissioning and several site-specific examples of completed decommissioning activities.


  • NCRP will establish a scientific committee to review current methods used to incorporate procedures/administration
  • routine monitoring – environmental, workplace, air monitoring, passive;
  • dosimetry program;
  • emergency planning;
  • staffing assignments/integration with contract staf;f
  • regulatory oversight and interface;
  • integration of required operational and decommissioning activities;
  • field implementation – posting/labelling, training requirement changes;
  • shipping/waste;
  • Multi-Agency Radiation Survey and Assessment of Materials and Equipment (MARSAME); and
  • lessons learned.


This new report will provide guidance to the Radiation Safety Program (staff) for use during the transition from an operating facility to a radiation safety program supporting decommissioning activities at U.S. Nuclear Regulatory Commission, U.S. Department of Energy and state-regulated facilities. The report will include lessons learned from completed decommissioning projects, recommended considerations/actions and program modifications to ensure the safe, compliant and effective implementation of radiation safety program principles throughout.
