Job Description

We have an opening for a Health Physicist. You will provide advanced health physics (HP) support to various LLNL Programs as well as provide support and guidance to other ES&H team members. This position is in the Environment, Safety and Health (ES&H) Directorate.  The primary assignment is in the Integrated Safety Team supporting LLNL institutionally managed facilities, including their decontamination and disposition.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will 

  • Provide advanced HP solutions for LLNL Programs in specific areas of assignment including but not limited to: establish appropriate personnel dosimetry, bioassay, and whole-body counting programs and evaluate the results of these monitoring programs; evaluate and provide radiation safety input to safety procedures and to facility, equipment, and shielding designs, and represent the organization as the technical resource on tasks and projects.
  • Prepare, execute and/or provide quality control for investigations of contaminated real property, materials and equipment (M&E) using laboratory policies, procedures, consensus guidance and standards, including MARSSIM and MARSAME; interpreting results and implementing actions for impacted sites.
  • Anticipate, identify, and evaluate HP-related hazardous conditions and practices to protect personnel from the effects of ionizing radiation through knowledge of engineering and science. Develop, evaluate, and implement radiation protection programs for workers during investigation and remediation of impacted sites and handling of contaminated M&E.
  • Conduct building inspections to identify and evaluate potential hazards related to HP and provide guidance for analyzing such hazards; provide guidance to LLNL Programs on all matters related to radiation protection and feedback to management regarding the effectiveness of the radiation safety program in their areas of responsibility.
  • Develop discipline action plan (DAP) to ensure effective radiological monitoring and control of workplaces and areas. Oversee the health and safety technicians’ performance of DAP activities. Review monitoring results and make recommendations to the Program to control associated hazards.
  • Provide selected training in radiation safety to personnel in the assigned area. Develop and present safety courses in HP or related topics; mentor less experienced personnel.
  • Respond to radiological emergencies and incidents on site, investigate incidents or accidents involving radiation and make recommendations to all levels of management to prevent a recurrence; provide HP solutions during audits, inspections and site verifications by internal and external agencies.
  • Perform other duties as assigned.

Additional job responsibilities, at the TSS.4 level

  • Provide solutions to highly complex site investigation and remediation issues/problems where a high degree of ambiguity exists around techniques and approaches. Solutions require in-depth analysis of multiple tangible and intangible factors. Solution path is typically not known ahead of time. Use independent judgment to accomplish objectives.
  • Routinely interact with professional colleagues, internal senior management, and sponsor organizations across and outside the Laboratory on advanced technical and business areas and projects/programs related to health physics, site investigations and remediation.
  • Act as the prime radiation protection expert on large investigation and remediation projects that affect the laboratory’s long-term goals and objectives.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship
  • Bachelor’s degree in Health Physics, Nuclear Engineering, Radiation Physics, or Radiation Protection or the equivalent combination of education and related experience. Significant experience in HP or a related field with advanced knowledge of related state and federal regulations and other consensus standards.
  • Experience preparing safety plans and technical reports (e.g., safety analysis reports, monitoring plans); conducting safety audits and inspections; successfully working potential compliance issues with Program customers, and external inspectors and regulators.
  • Analytical, decision-making and problem-solving skills to evaluate, interpret, negotiate, recommend and implement actions/solutions for complex problems.
  • Effective organizational skills with attention to detail necessary to handle multiple complex tasks in a demanding environment with conflicting priorities, tight and changing deadlines, and frequent interruptions while providing high-level customer service and good follow through.
  • Experience working independently and in a team environment with a broad cross-section of people and organizations, managing complex projects, and meeting schedules. Advanced verbal and written communication skills necessary to effectively collaborate in a team environment and to present and communicate technical information to all levels of management both internal and external to the Laboratory, including regulatory agencies and key stakeholders. Demonstrated ability to negotiate, recommend and implement solutions to complex problems.
  • Significant experience leading independent HP work and training, conducting gap analysis, reviewing new health and safety standards, and providing technical direction/leadership to health and safety staff on HP related matters. 

Additional qualifications at the TSS.4 level

  • Significant experience supervising and/or mentoring activities of other radiological control personnel.
  •  Expert verbal and written communication, facilitation and collaboration skills to effectively lead a team, and present, explain and advise senior management and external sponsors on highly-complex topics.

Qualifications We Desire

  • Master’s, or higher degree in Health Physics, or another closely-related technical area.
  • Certification by the American Board of Health Physics.
  • Experience preparing and executing MARSSIM and MARSAME or equivalent, investigations of contaminated real property, M&E; interpreting results and implementing actions for impacted sites; operational health physics implementing radiation protection programs for workers during investigation and D&D of contaminated facilities and impacted sites.  Experience in waste characterization techniques.
  • Experience providing emergency response and participation in the investigation of incidents or accidents involving radiological hazards.
