MEMORANDUM OF UNDERSTANDING BETWEEN THE UNITED STATES DEPARTMENT OF ENERGY, DEPARTMENT OF DEFENSE, DEPARTMENT OF HEALTH AND HUMAN SERVICES, ENVIRONMENTAL PROTECTION AGENCY, NUCLEAR REGULATORY COMMISSION, DEPARTMENT OF HOMELAND SECURITY, AND OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION REGARDING THE CENTER FOR RADIATION PROTECTION KNOWLEDGE I. INTRODUCTION A. Purpose. The extension of this Memorandum of Understanding (MOU) between the Department of Energy (DOE), Department of Defense (DoD), Department of Health and Human Services (HHS), Environmental Protection Agency (EPA), Nuclear Regulatory Commission (NRC), Department of Homeland Security (DHS), and Occupational Safety and Health Administration (OSHA) (participating agencies) provides for the reaffirmation of a Center for Radiation Protection Knowledge (Center) at the Department of Energys Oak Ridge National Laboratory (ORNL), Environmental Sciences Division, Oak Ridge, Tennessee.

Under the MOU, the Center would continue to serve as a common resource to assist the participating agencies in the development and application of radiation dosimetry and risk assessment methodologies that are based on the best available scientific information. The Center would be responsive to the participating agencies and would be administered by DOE.

This MOU is intended to help maintain and preserve U.S. expertise in radiation dosimetry and to ensure that Federal radiation programs are based on the best available information and applied in a consistent manner. A list of Center accomplishments since the latest extension of the MOU (2015) is included in Appendix A.

1

B. Background. For over sixty years, the Dosimetry Research Team at ORNL has developed and implemented biokinetic and dosimetric models for evaluation of doses to tissues of the body arising from external radiation fields or intake of radionuclides. The models and databases derived from these models have been widely used by the Federal agencies and by national and international scientific bodies such as the National Council on Radiation Protection and Measurements (NCRP), International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency. Currently, ORNL is one of only four organizations in the world involved in computation of dose coefficients and reference bioassay data published by the ICRP, and it is the only organization with extensive experience and capabilities in developing and implementing biokinetic and dosimetric models and their associated databases. Specific capabilities of the Center include:

- Computational dosimetry using both stylized and voxel anthropomorphic phantoms;

- Biokinetic modeling of the transport of different elements in the human body;

- Compilation and evaluation of radionuclide decay data and the construction of environmental source terms;

- Dose reconstruction and radiological assessment from a variety of source terms; and

- Radiation dosimetry using spectral and dose measuring instruments.

The participating agencies, acting through the Interagency Steering Committee on Radiation Standards (ISCORS) 1, recognize a mutual benefit from interagency coordination of ORNL work performed for individual Federal agencies in the areas of radiation dosimetry and risk assessment. Recognizing the importance of these activities to the primary Federal agencies with regulatory and/or operational authority in radiation protection, ISCORS recommends that such coordination of activities be facilitated under an MOU between these Federal agencies.

The purposes of the Center are to maintain U.S. expertise in radiation dosimetry and to use that 1

The Interagency Steering Committee on Radiation Standards (ISCORS) is a voluntary interagency coordinating committee that operates under a Charter. ISCORS was established in 1995 at the urging of Senator John Glenn to, according to the Charter, foster early resolution and coordination of regulatory issues associated with radiation standards and guidelines. ISCORS is a useful forum for Federal agencies involved in radiation protection to share information and attempt to reach consensus on radiation safety-related topics.

expertise to help ensure that Federal radiation protection and risk analysis programs are based on the best available scientific information. The Center would be supported by and responsive to DOE, DoD, HHS, EPA, NRC, DHS, and OSHA and would be administered by DOE. The Center would be maintained in the Environmental Sciences Division at ORNL.

C. Authority. This MOU is entered into under the authority of Reorganization Plan No. 3 of 1970 (EPA); the Atomic Energy Act of 1954 (AEA), as amended, (EPA, DOE, and NRC); the Occupational Safety and Health Act of 1970 (OSHA); the Energy Reorganization Act of 1974 (DOE and NRC); the Energy Policy Act of 2005 (DOE); the Public Health Service Act (HHS); the Food, Drug and Cosmetic Act of 2013 (HHS); Homeland Security Act of 2002 (DHS); and the Department of Energy Organization Act of 1977 (DOE).

Each participating agency asserts the following authority:

- DOE has authority under the AEA, the Energy Reorganization Act of 1974, and the Department of Energy Organization Act of 1977, to operate a system of laboratories and research centers concerned with the development of alternate sources of energy and studies on the biological and environmental impacts associated with energy sources and the assembly, disassembly and stockpiling of nuclear weapons. DOE has responsibility for assuring adequate protection of workers at its facilities, the public residing near these facilities, and protection of the environment at operating facilities and during cleanup of facilities and sites previously associated with its activities. DOE issues regulations and directives which it enforces at Departmental and DOE-contractor worksites to ensure this protection.

- DoD has a wide variety of activities related to the conduct and control of medical and military uses of radiation and radioactive materials, including cleanup and disposal of radioactive materials on military property. The DoD Components prepare manuals and procedures describing radiation protection activities applicable to their specific needs.

- HHS, through its Operational and Staff Divisions, has authority under the Public Health Service Act (42 USC) and the Federal Food, Drug and Cosmetic Act (21 USC) (as amended by the Pandemic and All-Hazards Preparedness Reauthorization Act of 2013) for the 3

conduct of health studies and the provision of guidance, assistance, and information on both health matters and health emergencies. This includes studies into the biological effects of ionizing radiation and response to radiological emergencies. HHS protects the public health and safety by preventing the adulteration of or controlling adulterated products such as foods, drugs, cosmetics, medical devices, animal feeds, and human biological products. It also protects the public from the dangers of electronic product radiation. HHS also has responsibility for assuring adequate protection of workers at its facilities who may use or be exposed to ionizing radiation, the public residing near these facilities, and protection of the environment at operating facilities.

- EPA is responsible under the AEA (42 U.S.C. 2021(h)) to advise the President with respect to radiation matters directly or indirectly affecting health and to recommend guidance to Federal agencies in the formulation of radiation protection standards. EPA is also responsible for setting generally applicable environmental radiation standards under the AEA and for regulating radionuclides under the Clean Air Act and the Safe Drinking Water Act. EPA also responds to radiological incidents and cleans up contaminated sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980. EPA issues guidance to Federal agencies and standards and regulations in pursuit of these activities.

- The NRC, created by the Energy Reorganization Act of 1974, exercises regulatory authority under the AEA. The NRC is responsible for regulating civilian applications of nuclear power and research reactors, isotope enrichment facilities, nuclear medicine, industrial and research applications of radioisotopes, and radioactive waste disposal.

NRC conducts research and develops standards and regulations to support its regulatory activities.

- Under the Homeland Security Act of 2002 (Public Law 107-296, 2002) as amended by the Countering Weapons of Mass Destruction Act of 2018 (Public Law 115-387) (6 U.S.C. 592(a)), DHS is responsible for ensuring the safety and security of the United States from terrorism, and both man-made and natural disasters, including those involving chemical, biological, radiological and nuclear (CBRN) threats. It was created in the aftermath of the terrorist attacks of September 11, 2001. DHS has focused largely 4

on prevention and response to terrorism within the U.S. in conjunction with its related responsibilities for border security, customs, emergency management, and critical infrastructure protection.

- OSHA is responsible, under the Occupational Safety and Health Act of 1970 (OSH Act) (29 U.S.C. 651 et seq.), for assuring safe and healthful working conditions for workers. To carry out this responsibility, the OSH Act authorizes OSHA to promulgate and enforce occupational safety and health standards. Under section 6(b)(5) of the OSH Act for standards dealing with toxic materials or harmful physical agents, OSHA is required to promulgate a standard that reduces, to the extent that is technologically and economically feasible, significant risk of material impairment of employees health (29 U.S.C. 655(b)(5)). OSHA adopted its existing ionizing radiation standard in 1971 (29 CFR 1910.1096). That standard applies to all working conditions in the private sector except those with respect to which other Federal agencies, such as DOE and NRC, and State agencies acting under section 274 of the AEA, as amended (42 U.S.C. 2021), have exercised statutory authority to prescribe or enforce standards or regulations affecting occupational safety or health (29 U.S.C. 653(b)(1)). Section 20(c) of the OSH Act specifically authorizes OSHA to enter into agreements with public agencies and private organizations to conduct studies relating to its responsibilities under the OSH Act (29 U.S.C. 669(c)).

CRPK capabilities Many of the capabilities of the Center for Radiation Protection Knowledge are listed below. The list includes capabilities that are available or can be generated by calling upon ORNL resources including the Centers association with other scientists:

• Computational Dosimetry using both stylized and voxel anthropomorphic phantoms including:

o Use of Monte Carlo and other radiation transport methods to compute dose coefficients for external exposure as well as internal irradiation of the human body.

o Construction of anthropomorphic phantoms for dosimetry studies.

o Development of phantoms for dosimetry and biokinetic modeling relevant to animals, particularly in emergency response situations.

o Integration of the above capabilities into a variety of facility analyses, e.g. the computation of dose to individuals due to activation products in materials or radionuclide contamination in the decommissioning of a facility.

o Benchmarking of Monte Carlo methods against direct measurement in the zero-scatter dosimetry calibration laboratory at ORNL (RADCAL/RASCAL).

Capabilities for neutron, gamma-ray and beta irradiation measurements are available.

• Biokinetic modeling of elements and compounds in the human body. CRPK personnel can generate both basic physiological system models and element-specific models.

o Supports the organ dose calculations for internal dosimetry needs.

o Supports dose reconstruction as the biokinetic models are designed for interpretation of radionuclide bioassay.

o This capability can also be directed at intakes for other purposes, such as the intake of chemical toxins.

• Compilation and evaluation of radionuclide decay data and construction of environmental source terms.

• Dose reconstruction and radiological assessment directed at accidental exposures and exposures from a variety of sources terms, including transport through the biosphere and atmosphere.

• Radiation dosimetry using both spectral and dose measuring instruments as well as simulations to support the interpretation of instrument readings.

o Supports development of improved dosimetry instruments through collaborations within ORNL.

o Examples:

Neutron dose measurements in facilities and reactors to generate field adjustment corrections to personnel dosimeter readings.

17

Simulation of instrument response to contamination in or on a person for use in an emergency response screening situation.

• Conduct radiation protection dosimetry-based measurements at nearby facilities, such as the Oak Ridge Associated Universities (ORAU), Oak Ridge Institute for Science and Education (ORISE), the Radiation Emergency Assistance Center/Training Site (REAC/TS), and the Nuclear Power Reactors of the Tennessee Valley Area, in collaboration with those entities. Examples include:

o Skyshine evaluation from Independent Spent Fuel Storage Installations o Pulsed, 14-MeV neutron and Cf-252 irradiation facilities o 6-MV pulsed LINAC o Spallation Neutron Source

• Serves as a research hub that could be used to integrate the capabilities of universities and laboratories into a coordinated radiation protection research program and serves as a means to convey advanced radiation protection knowledge to young professionals.

• Serves as a center for investigation of radiation protection in nuclear medicine procedures and radiotherapy.

18

Selected projects for U.S. Federal agencies, 2015-present Accomplishments of the Center for Radiation Protection Knowledge (CRPK) since the extension of the MOU in 2015 are listed below. Participation in national and international radiation protection activities are listed, in addition to products delivered to specific U.S. federal agencies.

Current activities in both categories are also listed.

Department of Energy

• Revised DOE Standard 1196-2011, including an update of the age-specific internal dose coefficients and replacement of external dose coefficients based on a reference adult with age-specific values. Updated Derived Concentration Standards (DCS values) were also derived and tabulated. The DCS values are guidelines for radionuclide concentrations in environmental media based on current radiation protection practices for controlling exposure to members of the public. The DCS values reflect the age- and sex-specific composition of the population, usage of environmental media, and radiation dosimetry.

Age-specific biokinetic models were applied.

Environmental Protection Agency

• Issued final version of Federal Guidance Report 15 External Exposure to Radionuclides in Soil, Air, and Water: External Dose Coefficients for General Application.

• Issued Federal Guidance Report No. 16 Preliminary Version: Cancer Risk Coefficients for Environmental Exposure to Radionuclides -- Radionuclide-Specific Lifetime Radiogenic Cancer Risk Coefficients for the U.S. Population, Based on Age and Gender Specific Intake Rates, Dosimetry, and Risk Model U.S. Nuclear Regulatory Commission

• The book Advanced Radiation Protection Dosimetry was published by CRC Press (Francis and Taylor) with a copyright date of 2019. CRPK staff served as the general editors of the book written for the NRC. Chapters were prepared by a collection of ORNL and non-ORNL authors. The topics include advanced external and internal radiation dosimetry concepts and regulatory applications. The book is intended to provide a reasonably comprehensive treatise of the state-of-the-art in radiation protection with the overarching goal of providing useful knowledge management references for the NRC staff and others involved in radiation protection.

• Provided the technical basis for NRC efforts on I-131 Patient Release doses to the public, e.g. Estimated Doses to Members of the Public from Exposure to Patients with 131I Thyroid Treatment, ORNL/TM-2017/442, August 18, 2017.

• Updated Regulatory Guide 8.36, Radiation Dose to the Embryo/Fetus and expanded the set of radionuclides by ~50%. The rationale for the updated dose coefficients was strengthened over the approach used in the original Regulatory Guide.

• Maintained PIMAL software and delivered courses on its use through the NRCs Radiation Protection Code Analysis and Maintenance Program.

19

Centers for Disease Control and Prevention

• Performed dose reconstruction for plutonium workers as part of the Million Worker Study.
