Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have two openings forgraduate-level or recent graduate Health Physics summer interns in the Environment, Safety and Health (ES&H) Directorate. You will work under the direction of the Radiation Protection Functional Area Manager to complete a project, or series of projects, that combine hands-on experience with technical knowledge. You may interact with all levels of personnel at the Laboratory including managers, experimenters, technicians, and other personnel that may be outside the ES&H Directorate.

Essential Duties
- Under the direction of LLNL staff, and as time permits, you will work individually or in collaboration on one of two main projects and other projects.
Main Projects:
1. Investigate x-ray ratios for wound counting depth correction Human tissue affects radiation interaction. Knowing how a known (type and energy) source of radiation is attenuated by human tissue in a particular area of the body allows for quick estimation of the radiation source depth in the wound and informs medical intervention. Using Monte Carlo N-Particle transport code, empirical measurements using LLNL counting systems, phantom materials, and radiation sources, you will investigate x-ray behavior dependent on energy, depth, and tissue composition. The result will be derived detection efficiency expressed as depth correction factors, which can be used in real-world accident scenarios.
2. Determine environmental radon ratios at equilibrium at LLNL facilities The presence of radon on air samples interferes with the ability to discern environmental radon from airborne occupational radionuclides. Knowing alpha/beta-gamma ratios of radon at equilibrium allows for field determination of the presence of radionuclides of concern. Using portable equipment to collect air samples at various locations of interest around LLNL and counting instruments, you will compile and evaluate air sampling data to determine alpha/beta-gamma ratios at equilibrium.
Other (potential) projects:
- Develop material for online training courses on the safe handling of Tritium and Plutonium using LLNL existing training material and DOE guidance.

- Must be a college or university student pursuing a graduate degree in health physics, nuclear engineering, or a closely related technical field, or a recent bachelors or masters graduate within one year.
- Ability to apply scientific methods to solve a defined problem or study question.
- Excellent oral and written communication skills.
- Proficiency with standard Microsoft Office suite including Outlook, PowerPoint, Word and Excel.
- Ability to work independently as well as in a team environment.
- Strong analytical skills.

Desired Qualifications
- Ability to apply basic and fundamental health physics concepts in a work environment.
- Experience in research and/or laboratory-type work settings as well as experience or working knowledge in mathematics and science.
- Demonstrated academic achievement in subject matter associated with radiation safety.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance: None required.

Note: This is a Temporary Student Intern appointment. This assignment is fora full-time position during the summer academic break. Selected applicants will be required to provide transcripts. Refer to the Scholar Program website at for additional student employment information.
