A brief summary on Marking UCNI Documents and Material.
Once an UCNI Reviewing Official has determined that a document or material contains UCNI, the document or material must be marked to ensure its protection. First, though, it is important to understand what constitutes a document and material as defined in 10 CFR 1017.4.
- Document means the physical medium on or in which information is recorded, regardless of its physical form or characteristics.
- Material means a product (e.g., a part or a machine) or substance (e.g., a compound or an alloy), regardless of its physical form or characteristics.
