Welcome to RED²

The Radiological Engineering, Detection, and Dosimetry (RED²) Laboratory in the Nuclear & Radiological Engineering and Medical Physics Programs in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology is led by Dr. Shaheen Dewji. The RED² Laboratory’s research focuses on harnessing both computational capabilities in Monte Carlo radiation transport modeling and experimental measurements for applications in radiation detection, radiation protection and shielding, dosimetry, health physics, and nuclear materials accounting.

RED² research activities include:

Computational Dosimetry

  • Development of dose coefficients using age/sex-specific anthropomorphic computational phantoms and radionuclide biokinetic models for occupational nuclear workers, members of the public, nuclear medicine, space, defense, and emergency response;
  • Innovative approaches harnessing Monte Carlo and hybrid radiation transport methods, as well as machine learning capabilities, are greatly enhancing radiation dosimetry science in these fields.

Radiation Detection

  • Employment of validation and verification of gamma-ray spectroscopic detector responses for contaminated environmental media for environmental assessment and decommissioning.
  • Field triage assessment of radiation uptake during nuclear, radiological, and fission product release events;
  • Nuclear materials control, accounting, and safeguards of special nuclear material using gamma isotopic monitoring and neutron multiplicity counting.
