What does the term 'RD' encompass?

The term 'RD' refers specifically to Restricted Data, which encompasses information related to the design, manufacture, or utilization of atomic weapons and atomic energy. This category of data is highly sensitive and is subject to stringent handling and protection requirements due to its significance to national security. Restricted Data is outlined in the Atomic Energy Act, and access to such data is limited to authorized individuals who have the necessary clearance.

The concept of special handling applies to Restricted Data since it requires additional measures beyond standard classification protocols. These measures can include specific storage requirements, restricted access to information, and limits on who may share or disseminate the data. Understanding this distinction is critical for anyone working in environments where classified information is prevalent, as mishandling RD data could have serious implications for national security.
