Dose modeling and assessment

ORAU offers dose modeling and assessment services to help mitigate radiological exposure risks

When the safety of your workers and the public is at stake, you need accurate and reliable dose assessments to demonstrate that federal and/or state regulatory compliance requirements are being met.

ORAU offers dose modeling and assessment services in support of safety evaluations, regulatory compliance evaluations, standards development and regulatory rulemaking.

Our experience and proven performance enables our highly qualified health physicists to perform dose modeling and assessments to ensure that radiological dose is “as low as reasonably achievable” or ALARA. We use a variety of technical methods to provide a solid dose estimate to ensure the safety of your workers, the public and the environment.

We also provide dosimetry in support of radiological facility audits. When a facility goes through the multiple steps in a U.S. Nuclear Regulatory Commission license termination process, the derived concentration guideline levels (DCGLs) must be determined to define cleanup levels that will meet regulatory requirements. ORAU adopts a reasonable, yet conservative approach to this analysis, using industry-accepted software codes and site-specific data.

Our experienced staff of health physicists, certified health physicists, and nuclear engineers have participated in dose modeling and assessment projects including:

  • Derivation of DCGLs for the Curtis Bay and Hammond Depots
  • Vermont Yankee Nuclear Power Station dose assessment study
  • Radium timepiece dose modeling

Our extensive capabilities with dose modeling software, including RESRAD-BUILD, Visual Sample Plan (VSP), Microshield, and MCNP, have also enabled us to support dose reconstruction projects for the Defense Threat Reduction Agency (DTRA) and the National Institute for Occupational Safety and Health (NIOSH).
