The Domestic Nuclear Detection Office (DNDO) is mandated by Congress to set Technical Capability Standards (TCSs) and implement a test and evaluation program for preventive radiological/nuclear (Rad/Nuc) detection equipment in the United States.
The Graduated Rad/Nuc Detector Evaluation and Reporting (GRaDERSM) Program evaluates commercial off-the-shelf (COTS) Rad/Nuc detection equipment against national consensus standards adopted by the Department of Homeland Security and TCSs.
- Identify radiation detection products that comply with standards and satisfy Homeland Security mission requirements
- Enable federal, state, local, tribal and territorial agencies to make more informed radiological/nuclear detector procurement decisions
- Provide infrastructure for the collection of high integrity test data
- Use National Voluntary Laboratory Accreditation Program (NVLAP) lab accreditation process to confirm test lab capability and competence
- Identify instrument categories, applicable standards, reporting protocols and compliance levels
- Become a self-sustaining testing program
- Manufacturers pay for voluntary testing by NVLAP accredited labs on their own schedule
- Labs submit for and maintain accreditation
- Standardize instrument testing procedures and presentation of test results to assure valid and easily interpreted comparisons
- Develop government post-market surveillance program to track products already evaluated under the GRaDER program
