Long-time nuclear waste warning messages

Long-time nuclear waste warning messages are intended to deter human intrusion at nuclear waste repositors 10,000 or more years into the future. The study of sign processes (semiotics) for the purpose of creating such long lasting messages where first done by the Human Interference Task Force in 1981. Sandia National Laboratories proposes in 1993 that the messages should invoke the following non-linguistically through signs and pictography;

''This place is a message... and part of a system of messages... pay attention to it!''

''Sending this message was important to us. We considered ourselves to be a powerful culture.''

''This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.''

''What is here was dangerous and repulsive to us. This message is a warning about danger.''

''The danger is in a particular location... it increases towards a center... the center of danger is here... of a particular size and shape, and below us.''

The danger is still present, in your time, as it was in ours.

The danger is to the body, and it can kill.

The form of the danger is an emanation of energy.

''The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited.''
