Manage and maintain radioactive materials licenses, permits, amendments, and renewals; prepare and submit technical exhibits, safety analyses, and regulatory filings to federal and state agencies.
Plan, coordinate, and conduct routine and special radiological surveys and contamination monitoring (surface contamination, airborne radioactivity, smear tests) to detect and quantify radiation and contamination levels and to validate control measures.
Administer and oversee the personnel dosimetry program, including selection of dosimeters, assignment, recordkeeping, dose assessment, dose investigations, ALARA reviews, and annual dose reporting to regulatory authorities.
Design, implement, and oversee environmental monitoring and effluent release programs, including sampling plans, analytical requirements, and interpreting results to ensure compliance with discharge limits and protect the public and environment.
Lead radiation incident response, emergency preparedness and drills, including on-call incident management, event characterization, remediation, personnel decontamination, dose reconstructions, root cause analysis, and regulatory notifications.
Conduct radiological hazard assessments and job-specific worksite evaluations to support safe work planning, radiation work permits (RWPs), job hazard analyses (JHAs), and pre-job briefings for maintenance, operations, and construction activities in controlled areas.
Provide technical support for shielding assessments and dose modeling using industry-standard tools (e.g., MicroShield, MCNP), develop shielding plans, and advise on facility design, temporary shielding, and work sequencing to minimize exposures.
Oversee and perform calibration, maintenance, and performance checks for radiation detection instruments and monitoring equipment (ion chambers, Geiger-Müller counters, scintillation detectors, air samplers) to ensure measurement quality and traceability.
Develop, deliver, and document targeted radiation safety training programs (new-hire orientation, refresher training, task-specific training, work authorization training) that meet regulatory training requirements and improve worker competency.
Implement and manage radioactive waste handling, segregation, packaging, labeling, storage, and transportation programs in compliance with DOT, NRC, and state regulations, including coordination of disposal vendors and manifesting.
Supervise contamination control programs and work area controls (containment, ventilation, negative pressure, HEPA filtration, glovebox operations), establishing airborne and surface contamination controls and release criteria for exiting controlled areas.
Perform internal audits, self-assessments, and readiness reviews of radiation safety programs and implement corrective action plans to address nonconformances identified during regulatory inspections or internal reviews.
Maintain comprehensive radiological records and technical files—dose histories, survey records, calibration certificates, training logs, license documents—and ensure data integrity, secure storage, and timely regulatory reporting.
Provide direct technical support to research, production, and maintenance teams by reviewing experimental designs and procedures involving radioactive materials, authorizing work, and approving control measures prior to startup.
Coordinate contractor and subcontractor radiation safety, including qualification, orientation, oversight during radiological work, and verification of contractor compliance with site radiological requirements.
Participate in multi-discipline safety committees and support the Radiation Safety Committee (RSC) or equivalent governance body by preparing reports, recommendations, and presentations to senior management and stakeholders.
Develop and implement occupational health surveillance and bioassay programs (urine, fecal, nasal smears, whole body counting) when working with internal contamination risks; evaluate results and recommend medical follow-up as needed.
Conduct dose reconstructions and exposure investigations following incidents or suspected overexposures; prepare technical reports and coordinate with medical personnel, regulatory agencies, and legal teams as required.
Lead continuous improvement initiatives for radiological controls, adopting best practices, lessons learned, and new technologies to optimize monitoring, reduce exposures, and improve program efficiency and stakeholder confidence.
Support decommissioning and remediation projects by performing radiological characterization surveys, scoping surveys for waste classification, and preparing technical documentation to support regulatory closure and release criteria.
Oversee procurement, lifecycle management, and quality assurance of radiation safety equipment, personal protective equipment, and monitoring systems; establish acceptance criteria and vendor qualification where necessary.
Provide subject-matter expertise in licensing actions, safety analyses, and risk assessments for new facilities, modifications, or experimental programs, ensuring radiological implications are fully integrated into project planning and design.
Coordinate with public affairs and community relations teams to craft clear, factual communications for stakeholders and the public regarding radiological events, routine monitoring results, and safety initiatives.

Secondary Functions

Provide periodic support to cross-functional safety and environmental audits; implement corrective actions stemming from integrated EHS assessments.
Assist in budgeting and resource planning for radiation protection programs, equipment purchases, and training initiatives.
Mentor and develop junior health physics staff; participate in hiring, performance reviews, and workload planning for the radiation protection team.
Collaborate with procurement and facilities teams to ensure vendor-supplied radioactive sources, equipment, and shielding meet specification and regulatory requirements.
Support research and development teams with risk assessments and radiation safety input for grant proposals, experimental protocols, and operational startup checklists.
Maintain professional development through attendance at industry conferences, participation in professional societies (e.g., HPS, NCRP), and tracking changes in regulatory requirements and guidance documents.
Contribute to organizational safety culture by participating in safety campaigns, toolbox talks, and promoting continuous learning about radiological hazards.
