Long-time nuclear waste warning messages

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 in 1981.
A 1993 report from Sandia National Laboratories recommended that any such message should comprise four levels of increasing complexity:
Message.
The Sandia report aimed to communicate a series of messages non-linguistically to any future visitors to a waste site. It gave the following wording as an example of what those messages should evoke:
Written messages.
The Waste Isolation Pilot Plant has done extensive research in development of written or pictorial messages to warn future generations. Since today's written languages are unlikely to survive, the research team has considered pictograms and hostile architecture in addition to them. Texts were proposed to be translated to every UN written language. In 1994, Level II, III, and IV messages in English were translated into French, Spanish, Chinese, Arabic, Russian, and Navajo, with plans to continue testing and revision of the original English text and subsequent eventual translation into further languages.
Conceptual designs for the Waste Isolation Pilot Plant included an "Information Center" at the geometric center of the site. The building would be an open structure of solid granite or concrete, measuring , and contain Level IV messages. The plans included a suggestion that the building be designed so as to create a distinctive whistling sound when wind blew through it, drawing attention to itself.
Working as part of the Human Interference Task Force in 1981, Vilmos Voigt from Eötvös-Loránd University (Budapest) proposed the installation of warning signs in the most important global languages in a concentric pattern around any terminal storage location. As time passed, further signs would be added translating the earlier signs, with the earlier ones remaining in place.
Physical markers.
The Sandia report explored designs for physical markers which conveyed the concepts of dangerous emanations, shapes that evoke bodily harm, and the concept of "shunned land" that appears destroyed or poisoned. The designs suggested included:
Cultural memory.
Linguist Thomas Sebeok, building on earlier work by Alvin Weinberg and Arsen Darnay and working as part of the Human Interference Task Force, proposed the creation of an "atomic priesthood", a panel of experts comparable to the Catholic church, which has preserved and authorized its message for almost 2,000 years. The priesthood would preserve the knowledge of radioactive waste's locations and dangers through rituals and myths.
French author Françoise Bastide and Italian semiotician Paolo Fabbri proposed that domestic cats be genetically engineered to change color in the presence of dangerous levels of radiation. The significance of these "radiation cats" or "ray cats" would be reinforced through fairy tales and myths, the story being that one should move away from sites where such creatures are encountered, or where domesticated cats begin to exhibit such behaviour. In 2014, musician Emperor X wrote such a song called "Don't Change Color, Kitty", designed to be "so catchy and annoying that it might be handed down from generation to generation over a span of 10,000 years".
