Welcome to RED²
The Radiological Engineering, Detection, and Dosimetry (RED²) Laboratory in the Department of Nuclear Engineering at Texas A&M University 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, dosimetry, health physics, and nuclear materials accounting.
Computational Dosimetry: Research activities include the 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: Research activities include the 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; and nuclear materials control, accounting, and safeguards of special nuclear material using gamma isotopic monitoring and neutron multiplicity counting. Machine learning in neutron spectral unfolding is a forefront capability being developed for nonproliferation applications .
Nuclear Safety, Security & Nonproliferation Policy, and Nuclear Knowledge Management: Research activities include evaluation of nuclear safety, security, and nonproliferation policy, including low dose regulation, nuclear safeguards and nonproliferation, emergency response, nuclear forensics (and here), and nuclear knowledge management (and video here).
RED² nuclear security research is conducted under the umbrella of the Center for Nuclear Science and Policy Initiatives (NSSPI) at Texas A&M University. Visit the NSSPI website regularly to check out the latest news and activities in nuclear security research, education, and training..
