Decontamination & Decommissioning
We are helping our customers prevent schedule inefficiencies and overspending by carefully planning and designing site characterization and final status surveys.
With a team of health physics experts who have extensive field experience, ORAU knows the support your decontamination and decommissioning project needs—from the characterization phase to the final status survey. We understand the risk of cost overruns, the necessity of high quality characterization, the difficulty of collecting accurate data and all other obstacles contractors and government agencies face on-site during the decontamination and decommissioning process.
In order to provide your remediation project with the support you need, ORAU’s team of health physicists and radiological experts have the necessary experience, procedures and instrumentation to design and implement characterization and final status surveys. Our experts customize these surveys to achieve high-quality, defensible data, and reduce risk for efficient and cost-effective cleanup. With high quality standards, ORAU survey results instill trust and confidence that public health and safety is protected following your site’s cleanup.
After years of proven expertise, ORAU has become a trusted partner to regulators and DOE affiliates in the environmental management community, including federal, state and local governments. ORAU also serves as the primary independent verification contractor and property release technical expert for the U.S. Nuclear Regulatory Commission.
As a leader in the health physics industry, ORAU’s has been instrumental in developing new environmental assessment standards. ORAU health physics experts were involved with writing the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM), now the nationally recognized standard for planning and executing radiological surveys. Other manuals and standards ORAU has helped develop include:
- Manual for Conducting Radiological Surveys in Support of License Termination (NUREG/CR-5849)
- Background as a Residual Radioactivity Criterion for Decommissioning (NUREG-1501)
- A Nonparametric Statistical Methodology for the Design and Analysis of Final Status Decommissioning Surveys (NUREG-1505, Rev. 1)
- Minimum Detectable Concentrations with Typical Radiological Survey Instrumentation for Various Contaminants and Field Conditions (NUREG-1507)
- Radiological Surveys for Controlling Release of Solid Materials (NUREG-1761)
- Performance and Documentation of Ionizing Surveys (ANSI N13.49)
- Characterization of Land Areas and Structures in Support of Decommissioning (ANSI N13.59)
- Training Requirements for Homeland Security Responders Using Radiation Detection Instruments (ANSI N42.37), which also references:
- Use of personal radiation detectors (ANSI N42.32)
- Portable radiation detection instruments (ANSI N42.33)
- Portable radionuclide identifiers (ANSI N42.34)
- Portable radiation monitors (ANSI N42.35)
