Radioecological Analysis

SC&A’s radioecologists provide specialized expertise in evaluating the fate and effects of radionuclides in the environment, part of the ecological and human health impact assessments required by many environmental statutes and regulations. Our services include:

  • Literature review and data collection on radionuclide levels in the environment and their fate and effects on humans and other organisms
  • Multimedia pathway modeling using the RESRAD suite of computer codes to assess impacts
  • Natural resource damage assessments using RESRAD-BIOTA
  • Support of site characterization and remediation in accordance with Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) protocols
  • Air and water permit preparation, including National Pollution Discharge Elimination System (NPDES) and Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) permits

Sample Projects

  • For a private company under contract with several state and federal agencies, SC&A supported natural resource damage assessments at uranium mines, the Hanford Nuclear Reservation, Los Alamos National Laboratory, and Oak Ridge National Laboratory.
  • For the New Mexico Environmental Division, SC&A derived radioecological screening levels for the Comprehensive Environmental Response, Compensation, and Liability Act/Resource Conservation and Recovery Act (CERCLA/RCRA) review of Yucca Mountain.
  • For the Republic of the Marshall Islands, SC&A evaluated the human health and radioecological behavior of residual contamination from above-ground nuclear weapons testing.
  • For U.S. Department of Energy facilities nationwide, SC&A has performed risk assessments for CERCLA and RCRA corrective action.
