Shaheen A Dewji

Radiological Scientist, Center for Radiation Protection Knowledge, Environmental Sciences Division

Shaheen Dewji is a scientist at Oak Ridge National Laboratory in the Center for Radiation Protection Knowledge. Her recent work has included assessment of patient release criteria for iodine-131 patients for the U.S. Nuclear Regulatory Commission, as well as updates to the U.S. Environmental Protection Agency's Federal Guidance Report (FGR) 12 on external exposure to radionuclides in environmental media and FGR 13 on dose coefficients and radiation risk associated with the inhalation and ingestion of radionuclides. Prior, Dr. Dewji spent five productive years with the Safeguards and Security Technology Group as a Nondestructive Assay Systems Engineer, where she employed gamma-ray methods for developing material control and accountancy for front and back ends of the fuel cycle through verification and validation experiments in the Safeguards Laboratory on enrichment, holdup (MUF), and signature analysis.

As a nuclear engineer, Dewji completed her M.Sc. and Ph.D. in Nuclear and Radiological Engineering at the Georgia Institute of Technology, having studied at both the Atlanta, GA, USA and Metz, France campuses. Dewji received her B.Sc. in Physics from the University of British Columbia, where she participated in the Science Co-op and Education Abroad programs.

Dewji currently serves as a member of the National Council on Radiation Protection and Measurements (NCRP) - CC2 Meeting the Needs of the Nation for Radiation Protection, as well as serves as United States representative on the ISO/TC 85/SC2 - Population Monitoring Following a Radiological Accident international working group.

Dewji's specializations include:

Radiation Protection and Dosimetry

  • Internal and external dosimetry
  • Monte Carlo (MCNP) computational simulation of anthropomorphic phantoms
  • Radionuclide patient release following nuclear medicine procedures
  • Population monitoring during a nuclear or radiological (IND/RDD) event
  • Monte Carlo computational detector validation (NaI, LaBr3, HPGe) in contaminated environmental media 

Nuclear Material Control and Accountability

  • Monte Carlo detector validation (NaI, LaBr3, HPGe) with special nuclear material
  • Nuclear material control and accountability experimental measurements: Enrichment and hold-up (MUF)
  • Nuclear forensics and non-proliferation policy
