Mr. Ikenberry is a Certified Health Physicist (CHP) with 24 years of technical and project management experience in occupational and environmental health physics, accident analysis, and radiological assessment of the construction, operation, and closure of nuclear facilities and their legacy of radioactive contamination in the environment. He has been an invited expert to the Advisory Committee on Nuclear Waste (ACNW) of the U.S. Nuclear Regulatory Commission (NRC), is currently the Vice Chair of the American National Standards Institute (ANSI) Accredited Committee N13 on Radiation Protection, and is an Associate Editor of the journal Health Physics. He has been the author or coauthor of more than 60 technical reports, publications, and presentations, as well as an author and technical contributor to numerous environmental impact statements (EISs), environmental assessments (EAs), and other technical documents.Bill Kennedy
Mr. Kennedy has been involved in the development of environmental pathway and radiation dosimetry models used to assess potential health and environmental impacts that resulted from releases of radionuclides to the environment. He has specialized in the use of these models to evaluate alternatives in such areas as environmental dose reconstruction, radioactive materials transport, radioactive waste disposal, decommissioning of nuclear facilities, development of clearance levels, and evaluation of nuclear facility operating practices.
Over the past 25 years, Mr. Kennedy has led and contributed to a variety of commercial low-level waste disposal projects for the U.S. Nuclear Regulatory Commission (NRC), the Electric Power Research Institute, and private industry. He was a charter member of the Low-Level Radioactive Waste Performance Assessment Peer Review Panel for the U.S. Department of Energy (DOE), representing the Hanford Site. As a member of this Panel, he served as acting chair for the review of the Savannah River Site Saltstone and E-Area Vault disposal facilities. He served on or chaired working groups and peer review panels associated with DOE high- and low-level waste, which included a Headquarters working group to develop a technical basis for the low-level waste disposal Order, chair of a Headquarters working group to review proposed U.S. Environmental Protection Agency (EPA) low-level waste regulations, a Headquarters working group to advise and review proposed revisions to EPA high-level waste regulations, and working groups to review low-level waste disposal options at the Hanford Site.Ed Maher, Sc.D. , CHP
Dr. Maher is a Certified Health Physicist with more than 30 years of experience conducting and managing radiological, safety, and environmental protection programs applicable to commercial clients and Federal agencies such as the U.S. Departments of Energy (DOE) and Defense (DOD). He is a retired U.S. Air Force (USAF) Colonel with extensive experience in designing, developing, and implementing nuclear, biological, and chemical warfare defense strategies.
Dr. Maher has managed environmental, health, and safety organizations involved with risk management, emergency response, and business continuity planning. He directed the USAF Radiation Assessment Team responsible for providing immediate and global responses to nuclear weapon accidents. He led a comprehensive study on defensive actions to ensure nuclear plant control room habitability following a terrorist attack involving chemical warfare agents or toxic industrial chemicals. The study considered engineering, mechanical, personnel protective, and administrative actions for potential use against the full spectrum of chemical warfare agents and associated delivery systems.Dan Mantooth, CHP
Mr. Mantooth has over 30 years of experience in occupational and radiological safety and waste management and 10 years of line and project management experience. He has provided staff and consulting support to the U.S. Department of Energy (DOE), U.S. Department of Defense (DOD), U.S. Environmental Protection Agency (EPA), and commercial power operations. His key areas of expertise include occupational and radiological safety program management, development, implementation, and assessment. Mr. Mantooth’s technical strengths include laboratory occupational safety (laser safety, chemical hygiene), radiological engineering and design review, and safety aspects of decontamination and decommissioning. <\p>Steve Merwin, CHP
Mr. Merwin’s 22 years of experience cover a broad range of radiation protection and related disciplines including dose assessment, regulatory compliance, risk assessment, environmental health, and industrial hygiene. He has served as a manager, task leader, trainer, and contributor for programs and projects for the U.S. Department of Energy (DOE), the U.S. Nuclear Regulatory Commission (NRC), DOE contractor organizations, NRC licensees, the National Institute for Occupational Safety and Health (NIOSH), and private firms. Most recently, Mr. Merwin has played a significant role on the NIOSH Dose Reconstruction Project under the Energy Employees Occupational Illness Compensation Program Act (EEOICPA).
Mr. Merwin has given a number of presentations on such radiation protection topics as dose assessment, beta dosimetry, hot particles, and risk assessment. He has lectured at short courses on the management of radioactive and mixed waste, optimization of radiation protection programs, and hot particle exposures.Steve Sohinki
Mr. Sohinki was a member of the Senior Executive Service for 17 years and has more than 30 years of experience in the field of nuclear energy (civilian and military uses). During his service with the U.S. Department of Energy (DOE), he managed major national security programs associated with the analysis of alternatives for the nuclear weapons complex of the future, the development of a new supply of tritium to support the nuclear weapons stockpile, as well as the Department’s safety enforcement program, which has contributed significantly to the improvement of safety performance throughout the DOE Complex. Before joining DOE, he had 14 years of legal experience on the regulatory and industry sides of commercial nuclear power. This experience includes representation of the Nuclear Regulatory Commission (NRC) technical staff in reactor licensing and enforcement proceedings, service on the personal staffs of two NRC Commissioners, and legal representation of and consultation for two commercial nuclear utilities. His accomplishments as a member of the Senior Executive Service resulted in his receipt of a Presidential Rank Award as well as several DOE commendations for outstanding service.David Waite, Ph.D. , CHP, CHMM
Dr. Waite is an internationally recognized expert in integrated safety management, radiological health, and waste management. He has over 40 years of experience in health physics, environmental radioactivity, nuclear and mixed waste management, risk assessment, and program management. He has international experience in the environmental safety and health community, as well as experience in high-technology line management and large Federal project management.Rob Winslow, CHP
Mr. Winslow has 24 years of experience in operational and technical radiation protection, including experience as a technical and operational health physicist at commercial nuclear power plants and U.S. Department of Energy (DOE) facilities. He has managed projects involving procurement, procedure development, and training on radiation monitoring systems. He has extensive experience with projects that required the practical application of radiation and contamination control techniques in operational and remediation projects. He has diverse health physics experience that includes facility shielding design use of computer modeling codes, procedure development, program administration, and operational health physics planning.Susan Winslow
Ms. Winslow has over 18 years of experience as a health physicist and as a radiation protection program manager at commercial nuclear power plants and U.S. Department of Energy (DOE) facilities. She has extensive experience in environmental restoration, radiological engineering, and decontamination and decommissioning projects at the DOE Hanford Site. She has managed projects requiring the development of technical basis documents and procedures that balance the practical application of radiation and contamination control techniques with regulatory requirements.
