Our Expertise

The RSEL’s association with the Georgia Tech NRE/MP Program, the George W. Woodruff School of Mechanical Engineering, and the Georgia Tech Office of Radiological Safety affords access to a range of low-level detection equipment, as well as to a machine shop with all labor costs 100 % subsidized by the Georgia Tech College of Engineering.  Further, Georgia Tech maintains a mobile site license for use and possession of radioactive materials.  This allows Georgia Tech scientists to conduct research anywhere in the State of Georgia, giving them a broader range of applicability and testing capabilities.  Thus, unlike many other research projects, laboratory walls do not bind NRE/MP research.  Our expertise spans both computational and experimental methods, while also providing exposure to the nuances and challenges of work with nuclear materials.

Quantitative and Qualitative Analysis

  • Gamma-ray spectroscopy using a range of instruments including:  NaI, CsI, LaBr, and HPGe.  Analyses use a range of off-the-shelf software (Genie2K, ISOCS, LabSOCS, Prospect, Maestro) as well as software developed by members of the NRE/MP Program.
  • Gas Flow Proportional Counting and Liquid Scintillation Counting for alpha and beta detetion.
  • Qualitative and quantive neutron methods using 3He, BF3, B10, Bonner sphere spectrometers, and scintillator detectors.  A number of techniques are also being researched/developed using 3He alternatives.
  • Neutron Activation Analysis
  • Materials analysis

Medical Physics

Through the Medical Physics faculty at Georgia Tech, Emory University, and other affiliated organizations, the RSEL has access to expertise and experience in:

  • Image guided radiation therapy
  • Adaptive radiation therapy
  • Intensity modulated radiation therapy
  • Radiation dosimetry
  • Algorithm design for tomographic reconstruction
  • Cone Beam Computed Tomography
  • 3D and 4D computed tomography
  • Single photon emission computed tomography
  • Positron Emission Tomography
  • Respiratory gated fluoroscopy
Modeling and Simulation

  • Whole-core transport models for reactor physics analysis
  • Monte Carlo and deterministic radiation transport methods
  • Computational medical physics
  • Development of spectral deconvolution algorithms
  • Computational material science

Policy

Recognizing that the nuclear needs of the United States are not only technical, but political, the RSEL is uniquely suited to help train the next generations of nuclear engineers to understand the unique interplay of science and policy.  In addition to technical staff experienced in MC&A and Safeguards, our affiliations afford access to a range of individuals in the Department of Homeland Security, Department of Defense, and the Department of Energy.
