🔗 Linguistics 🔗 Energy 🔗 Linguistics/Philosophy of language

Long-time nuclear waste warning messages are intended to deter human intrusion at nuclear waste repositories in the far future, within or above the order of magnitude of 10,000 years. Nuclear semiotics is an interdisciplinary field of research, first done by the Human Interference Task Force since 1981.

A 1996 report from Sandia National Laboratories recommended that any such message should comprise four levels of increasing complexity:

• Level I: Rudimentary Information: "Something man-made is here"
• Level II: Cautionary Information: "Something man-made is here and it is dangerous"
• Level III: Basic Information: Tells what, why, when, where, who, and how
• Level IV: Complex Information: Highly detailed written records, tables, figures, graphs, maps and diagrams
