About Our Team

The Radiation and Nuclear Detection Systems department undertakes research and development of ionizing radiation and rare signature detection systems to address broad nuclear security needs in support of various US Government programs. Through internal collaborations our department targets applications in neutron generators, nuclear proliferation detection, nuclear non-proliferation, international safeguards, arms control treaty verification, radiological emergency response, and other national security objectives such as explosives detection.

Areas of significant experience and expertise include:
  • fission-energy neutron detection and imaging
  • anti-neutrino detection
  • weak source detection techniques
  • high-channel-count systems.

Our work includes a range of basic to applied research, and involves equipment at various technology readiness levels:
  • Basic Research (TRL 1-2) * Experimental study and characterization of radiation signatures encountered in nuclear security scenarios *
  • Conception and development of new radiation detection techniques
  • Development of radiation detection systems (TRL 3-4) * Feasibility studies and rapid detector system prototyping *
  • Laboratory tests of prototype systems: controlled experiments emulating relevant aspects of real-world scenarios
  • Field Experiments (TRL 5-6) * Deployment of mature detection systems to understand their performance in real measurement environments.
The department specializes in designing detection systems for the anticipated radiation signature and background for a specific application.

Using as much information in the expected radiation signature as possible, we design:
  • detectors for standoff detection and localization of radiological materials
  • detectors for rare event signatures
  • antineutrino and coherent neutrino scattering detection
  • high resolution imaging detection systems
  • Discriminate between point and extended radiation sources
  • Identify chemical elements in 3D through high-Z shielding
  • detectors in high background / high rate environments
  • active interrogation, above ground nuclear reactor monitoring, neutron generator monitors
  • Particle identification and discrimination

Security Clearance

This position does not currently require a Department of Energy (DOE) security clearance.
Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment.

If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals.

The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.


All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.
