Radiation Physicist, Level 3

Website SSRLnews SLAC National Accelerator Laboratory

Job ID: 5250
Full/Part Time: Full-Time
Regular/Temporary: Regular

Position overview:

We are seeking a Radiation Physicist to join our Radiation Protection Department (RPD) to support the design of shielding and radiation containment systems for the assigned accelerator facilities, projects, experiment, and provide support and oversight for their safe and efficient radiological operations. The assigned facilities may include the Linac Coherent Light Source (LCLS), LCLS-II and LCLS-II High Energy projects, FACET-II, MEC upgrade projects, Stanford Synchrotron Radiation Laboratory (SSRL), and/or test facilities

The Radiation Physicist will also carry out responsibilities for developing, implementing, and managing radiological protection programs to protect workers, users, the public and the environment to meet regulatory, and SLAC internal requirements. The Radiation Physicist will conduct comprehensive radiation hazard and risk analysis, perform shielding and activation calculations using state-of-the-art Monte Carlo radiation generation and transport computer codes and associated physics packages, such as FLUKA, assisting users and SLAC personnel in avoiding or minimizing radiation exposure and equipment damage.

In collaboration with staff scientists and engineers, project managers, technical and administrative personnel, users, contractors, regulators, and other stakeholders, the Radiation Physicist will develop operating procedures and program manuals including authorizing documents for commissioning and operation of accelerators, beam lines, and other radiation generating devices. Additionally, the Radiation Physicist is expected to conduct comprehensive, independent compliance assurance reviews of radiation safety programs, provide training and coaching to students, technicians, and other health physicists.

As part of the support and safe evaluation of accelerator facilities, the candidate should be able to work and communicate fluently with engineers and physicists to integrate designs with mechanical implementation of components, as well as engineering controls and procedures.

The Radiation Physicist is expected to develop new techniques, methods, and computer code capabilities to advance the radiation physics field, with subsequent publications in refereed journals.

This position reports to the Group Leader, or senior staff in the Radiation Physics Group (RPG) within RPD.

Note: SLAC is a U.S. Department of Energy (DOE) laboratory operated by Stanford University and based in Menlo Park; CA. 

Your specific responsibilities include:

  • Support the design of engineered radiation safety systems to mitigate radiation hazards, which include shielding calculations (using state-of-the-art Monte Carlo computer codes), interlocked access control systems, and beam containment systems for assigned SLAC facilities/projects.
  • Provide support and oversight for commissioning and safe operation for the assigned facilities.
  • Work independently to plan, design, manage, and evaluate the technical and operational functions of radiation safety programs.
  • Develop radiation safety program procedures and policies and ensure their implementation to meet regulatory, standards and SLAC requirements.
  • Serve as a technical subject matter expert (SME), providing functional direction, field oversight, and training in the overall application of radiation safety programs.
  • Provide oversight for safe and effective conduct of facility operation and radiological activities in assigned facilities.
  • Maintain field presence in support of staff and users in implementing radiation protection programs.
  • Provide support to the RPD Department Head and RPG Group Leader to meet the RPD and ES&H Division objectives.
  • Develop new techniques, methods, and computer code capabilities to expand and optimize shielding design capabilities.
  • Perform characterization of activation in high-energy particle accelerators by using codes such as FLUKA.
  • Conduct comprehensive, independent compliance assurance reviews of radiation safety programs. Develop and implement safety policies and procedures related to radiation protection regulations.
  • Conduct research and development, code cross-comparison and statistical analysis, and make presentations and publish papers in refereed journals.
  • Provide training and coaching to SLAC staff, users, and contractors.
  • May lead a team responsible for developing and implementing radiation safety programs.

To be successful in this position you will bring:

  • A Bachelor’s degree in health physics, radiation physics, medical physics, nuclear engineering, or related field and 8 years or a combination of education and relevant experience in the following:
  • Designing, supporting, and managing technical and operational functions of radiation safety programs.
  • Designing, developing, and optimizing radiation shielding, safety devices, and radiation machines.
  • Characterization and modelling of activated materials in high-energy particle accelerators using state of-the-art computer codes, such as FLUKA.
  • Radiological hazard identification, safety analysis, and dose, shielding, and activation calculations, using and developing state-of-the-art Monte Carlo codes, such as FLUKA.
  • Ability to train and coach technical staff and providing safety training to personnel.
  • Ability to conduct radiation safety risk assessment, mitigation, and crisis management.
  • Research and development skills to improve the methods and programs.
  • Ability to effectively communicate orally and in writing with diverse audiences and to explain technical concepts clearly and concisely.

In addition, preferred requirements include:

  • In the alternative, we will accept an equivalent combination of education and experience in the form of a master’s degree in health physics, radiation physics, medical physics, nuclear engineering, or a related field, and 6 years’ experience as specified; or a Ph.D. in health physics, radiation physics, medical physics, nuclear engineering, or a related field, and 4 years of experience as specified.
  • Knowledge and experience in radiation safety design and operations for large particle accelerators, and/or synchrotron or free-electron light sources.
  • Knowledge of numerical methods and sensitivity analysis of statistical data in benchmarking particle transport codes.
  • In-depth knowledge of radiation protection regulations at the federal, state, and local levels.
