Very interesting article, although I think it's a little unnecessary. It wouldn't take long for a nuclear waste site to become a Glow-like harbinger of doom for all the societies around it. Even if our distant descendants are primitive, they should still be able to grasp the concept of "Everyone who went there died."
Communicating the dangers of nuclear waste to unfathomably remote descendents may seem like a topic best left to third-drink philosophers in dorm rooms. It's actually been left to the most humdrum of all Cabinet-level departments after commerce, agriculture, and the interior: the Department of Energy, which oversees the disposal of radioactive trash at the Waste Isolation Pilot Plant near Carlsbad, N.M. According to government guidelines, DoE must plan for the continuing safety of the site over the next 10 millenniums.
Even if future trespassers could understand what keep and out mean when placed side by side, there's no reason to assume they'd follow directions. In "Expert Judgment," the panelists observe that "[m]useums and private collections abound with [keep out signs] removed from burial sites." The tomb of the ancient Egyptian vizier Khentika (also known as Ikhekhi), for example, contains the inscription: "As for all men who shall enter this my tomb … impure … there will be judgment … an end shall be made for him. … I shall seize his neck like a bird. … I shall cast the fear of myself into him." It's possible that the vizier's contemporaries took Khentika at his word. But 20th-century archaeologists with wildly different religious beliefs had no reason to take the neck-cracking threat seriously. Likewise, a scavenger on the Carlsbad site in the year 12,000 C.E. may dismiss the menace of radiation poisoning as mere superstition. ("So I'm supposed to think that if I dig here, invisible energy beams will kill me?") Hence the crux of the problem: Not only must intruders understand the message that nuclear waste is near and dangerous; they must also believe it.
