Core Responsibilities

Primary Functions

Develop, implement, and continuously improve a comprehensive Radiation Protection Program (RPP) aligned with ALARA principles, applicable NRC/DOE/EPA/OSHA regulations, and company policies to minimize occupational and public radiation exposures.
Conduct routine and special radiological surveys, contamination assessments, air sampling, and smear testing; interpret survey data and produce detailed technical reports and corrective action plans.
Perform dose assessments and exposure evaluations using personnel dosimetry, bioassay results, and environmental monitoring data; reconcile dose records and advise on dose reduction strategies.
Design, review, and optimize shielding solutions and radiation barriers in collaboration with mechanical and civil engineering teams using deterministic calculations and Monte Carlo modeling (e.g., MCNP, Geant4, or equivalent).
Lead radiological control for operations, maintenance, and outage activities, including characterizing work areas, authorizing radiological work permits (RWPs), establishing controls, and supervising radiological work practices.
Manage the personnel dosimetry program: select appropriate dosimeters, maintain records, interpret results, ensure timely distribution/collection, and communicate dose trends to management and workers.
Oversee radioactive waste characterization, segregation, packaging, labeling, storage, and disposition; coordinate with waste management contractors and ensure DOT/IATA shipping compliance.
Maintain and calibrate radiation detection and monitoring instrumentation (survey meters, contamination monitors, continuous air monitors, portal monitors); establish calibration schedules and vendor relationships.
Prepare, review, and maintain radiological safety procedures, technical safety analyses, safety basis documents, and licensing submittals for NRC/DOE/state permit compliance.
Develop and deliver site-specific radiation safety training and qualifications for operations, maintenance, contractors, and emergency responders; evaluate competency and maintain training records.
Serve as technical lead during radiological incidents and events: perform event investigations, root-cause analyses, dose reconstructions, corrective actions, and regulatory notifications and reports.
Coordinate and execute environmental radiological monitoring programs, assess effluent releases, support environmental sampling and laboratory analyses, and report results to regulatory agencies.
Support decommissioning, dismantlement, and remediation projects through radiological characterization, dose modeling, ALARA planning, and oversight of decontamination activities.
Provide on-call radiological support for field operations, emergency response drills, and real-world incidents, including acting as on-scene advisor for protective actions and remediation strategies.
Interface with external regulators and stakeholders: prepare and deliver inspection packages, respond to regulatory inquiries, and manage audit findings and corrective action closure.
Implement and monitor radiological work controls for sealed sources, unsealed radiological materials, and neutron sources; ensure secure inventory control and leak testing where applicable.
Conduct radiological modeling and source term evaluations to support safety analyses, shielding assessments, transport safety, and emergency planning scenarios.
Review engineering design changes, procurement specifications, and construction activities for radiological implications and provide design recommendations to minimize exposures.
Oversee contractor radiological performance: review health physics plans, authorize access, verify training and qualifications, and perform surveillance of contractor radiological work.
Maintain and audit radiological records, including personnel exposure histories, calibration certificates, survey logs, waste manifests, and shipping records, ensuring completeness and regulatory retention requirements.
Lead continuous improvement initiatives within the radiological program, including lessons learned, metrics tracking, program benchmarking, and integration of new instrumentation and technologies.
Prepare clear, technical, stakeholder-focused reports and presentations for operations, leadership, regulators, and the public that explain radiological risks, controls, and compliance status.

Secondary Functions

Support cross-functional projects that require radiation expertise, including design reviews, procurement evaluations, and facility modifications.
Conduct internal audits and surveillance of radiological work processes and contractor performance to ensure consistent application of RPP standards.
Maintain inventory and lifecycle management for radioactive sources, sealed source tracking, and licensing records.
Collaborate with medical, environmental, and industrial hygiene teams to integrate radiological controls into broader EHS programs.
Participate in corporate and site-level emergency planning committees, exercise development, and after-action reviews to strengthen radiological response capabilities.
Develop performance indicators and dashboards for radiological safety metrics (e.g., collective dose, contamination events, survey results) and provide periodic trend analysis to leadership.
Contribute to procurement specifications for radiation detection equipment, shielding materials, and contamination control supplies.
Assist in cost/benefit analyses for radiation protection investments, including engineering controls versus administrative controls and personal protective equipment (PPE).
Mentor and supervise junior health physics staff and technicians; provide performance feedback and professional development coaching.
Support research, testing, and commissioning activities that involve radioactive materials, ensuring safe work planning and regulatory compliance.
