Current Job Responsibilities Mr. Duncan has 24 years of professional health physics experience spanning the areas of internal dosimetry, radiation protection management, and risk assessment. Mr. Duncan's prior experience includes management of the University of Colorado Radiation Protection Program (RPP) for 11 years. This included maintenance and renewal of the Type A broad license covering three campuses, and development of policies, procedures, goals, staffing, budget requests, and quality assurance measures to ensure adequate safety and regulatory compliance. During his stay at the University, state inspection results improved to zero items of noncompliance. He also provided health physics technical support and human health risk assessment services for 8 years while employed with consulting firms. Consulting firm experience included marketing, proposal writing, project management, budgeting, staffing, and assisting with office management. Projects included managing CERCLA baseline human health risk assessments for several operable units at RFETS, writing the RFETS Nuclear Accident Dosimetry Technical Basis, conducting ALARA reviews, designing/conducting final radiation surveys, and providing risk-based corrective action (RBCA) for commercial clients. He has provided internal dosimetry services for Radiological Health at the Rocky Flats Environmental Technology Site (RFETS). He is qualified on in vivo bioassay lung and wound counter systems, and experienced performing dose assessments and prescribing in vitro bioassay based on workplace indicators. He contributed to Technical Basis Documentation, Procedures, and the Quality Assurance Plan to ensure compliance with DOE Regulations and Standards, including DOELAP for Internal Dosimetry. He also coordinated the RFETS Enhanced Air Monitoring Program meetings/documentation and served as subject matter expert for Nuclear Accident Dosimetry. Currently, Mr. Duncan is serving as an internal dose reconstructor for the National Institute of Occupational Safety and Health (NIOSH) Dose Reconstruction Program. He provides health physics support, including technical basis document and procedure preparation, dose reconstruction and data analysis, to assist with dose reconstructions for claimants under the Energy Employees Occupational Illness Compensation Program Act. He also evaluates data relevant to Special Exposure Cohort petitions, and performs dose reconstruction research.
