Qualifications We Desire

  • Ph.D. in Nuclear Engineering, Physics, Chemistry or related field
  • In-depth knowledge of radiation detection and measurement and associated equipment
  • Demonstrated technical expertise across a range of applications, including nuclear physics, x-ray and radioactive source-based irradiators, linear accelerators, nuclear medicine diagnostic and therapy instrumentation, and applications of radioisotopes in commercial industrial and medical settings.
  • Knowledge of or experience on NNSA’s programs in nuclear and radiological safety, security, and safeguards.
