Health Physicist

About the role

Design and ownership of radiological protection programs for a high-radiation prompt test environments. The role covers ALARA practices, dosimetry and bioassay programs, instrumentation/spectroscopy, shielding/activation analysis, environmental monitoring, waste and source control, procedure development, and audit readiness.

You will collaborate with Radiation Contamination Technologists (RCTs) and Test/Engineering to enable safe throughput and reliable data while meeting federal and state requirements.

Job Requirements

• Plan and execute radiation work procedures (RWPs)/ALARA for radiation generating operations (pulsed-power accelerators and neutron yields); establish boundaries, brief crews, and control access.
• Develop, implement, and maintain the site Radiological Protection Program (RPP); chair/coordinate ALARA reviews and dose trending for individuals.
• Author Radiation Work Permits and safety checklists for radiation generating operations; establish boundaries, postings, and access controls with RCT collaboration.
• Manage Dosimetry & Bioassay programs and extremity dosimetry monitoring of rad workers; determine bioassay requirements (urinalysis/thyroid counting), maintain exposure records and reporting.
• Regulatory understanding, negotiating, and implementation as required for regular operations
• Oversight of all radiological work and radiological protection including daily operations as well as high radiation areas and contamination scenarios.
• Perform quick-turn shielding/activation estimates (MCNP/GEANT4/NOVICE or validated simplified methods); recommend cell layouts, shielding, and radiation material area (RMA) criteria.
• Establish contamination control levels; oversee RCT decontamination practices of hardware, facilities, and personnel as required.
• Maintain surveys, chain-of-custody, calibrations, source inventory, and incident reports in controlled repositories
• Support experiment/test series planning and readiness reviews.

Job Requirements

• Minimum Qualifications
• Education: BS/MS in Health Physics, Radiological Engineering, Nuclear Engineering, or related field.
• Experience: 4–8+ years in radiological protection at accelerator, reactor, pulsed-power, HEDP, nuclear effects, or similar mixed-field environments.
• Expertise with radiation protection standards and safety processes.
• Experienced with MCNP/GEANT4/NOVICE (or equivalent) for shielding and activation modeling.
• Proficiency with survey meters, neutron rem counters, friskers, personal contamination monitors; meter calibration/response checks; sealed-source control and leak testing.
• Clear, concise technical writing; calm, direct communication with engineers, technicians, and external customers and reviewers.

Desired Skills

• Prior responsibility for DoD/DoE environmental monitoring programs and safety protocols
• Experience integrating rad controls with non-rad hazards (HV, vacuum, cryo, lasers) and broader EHS systems.
• Familiarity with PDM/PLM and document control practices; change control for procedures and drawings.
• Experience supporting classified or export-controlled programs; comfortable with customer interfaces (DoD/DoE primes).
• Quality, Safety, and Compliance Knowledge of NRC/Agreement-State rules, 10 CFR series (as applicable), DOE Orders/Guides, ANSI/HPS standards, and OSHA electrical/LOTO/ESD practices.
• U.S. person under ITAR/EAR definitions and clearance-eligible for certain programs (background check required).
