Seems like a good message to future generations would be long half-life radioactive material. Enough to detect but not to harm near the boundaries, and then a little bit more at the center so that there's a clearly indicated "this gets strong" idea. If civilization fails and they forget how to build a geiger counter, they aren't likely to be doing much tunneling 1000 feet down.
Also, the mutant sickly plants will be a good indicator.

Tobacco shows substantial resistance to radioactivity, especially considering virtually all tobacco contains Po-210. It also survives with isotopes of Plutonium, Polonium 209 and Americanium... amongst many other radioactive elements it can pick up and thrive despite.
- bdonlan 16y agoWhat makes you think understanding of radiation is necessary to dig? Even if they had that understanding, why would they bother using a geiger counter on an archaeological dig? And plants can adapt - chernobyl is quite hazardous, but plant life still grows there, and there's no guarentee that any effects on their growth will be understood (and any level of radiation enough to _really_ effect them will effect people standing on the surface too)
