In regards to restricted data, what is NOT considered?

The correct answer highlights that public disclosures of safety information are not considered restricted data, primarily because restricted data specifically refers to information related to the design, manufacture, or utilization of atomic weapons, as well as information on nuclear materials. Publicly available safety information, on the other hand, is typically disseminated to ensure the safe use and management of nuclear facilities and materials, adhering to transparency and regulatory standards.

In contrast, details on weapon designs, manufacturing processes of nuclear materials, and information on operational theories all fall under the definition of restricted data. These categories involve classified information that could potentially compromise national security if disclosed. Thus, they are subject to stringent controls and are not available to the public, aligning them with the framework of what constitutes restricted data.
