Atomic semiotics

Atomic semiotics (or nuclear semiotics) is an interdisciplinary field of semiotics which studies potential uses of long-term nuclear waste warning messages. It is concerned with labelling radioactive waste to deter human intrusion at nuclear waste repositories in the far future.

Currently used warning sign for Radioactivity, W05: "Warning of radioactive substances or ionizing radiation“

ISO 21482 warning used since 2007, which is more explicit

Elements of the message

The message must contain three elements:

That it is a message
That the substances put in a specific place are dangerous
Information about the kind of danger which comes from these substances

The message must also be credible. If it isn't credible it will be understood, but neglected; people will believe that this is done to protect an important treasure. These substances must be safe for 10.000s to millions of years.
