Isn't there some level of radiation that is ubiquitously present ever since we started nuclear testing? Seems like we could figure out if there ever was a nuclear-capable society in the past just by looking at radiation decay.
- dec0dedab0de 7y agoI think the show ancient aliens claimed that a site (or sites?) Had measurable radiation from an ancient explosion.
- ianai 7y agoWho knows what they were referencing, but there is a site of a “natural nuclear reactor”. They could have built a lot off that.
- dredmorbius 7y agoThe Oklo and Bangome natural uranium fission reactor sites, dating to about 2 bya, are in what is now Gambia, Africa. https://blogs.scientificamerican.com/guest-blog/natures-nuclear-reactors-the-2-billion-year-old-natural-fission-reactors-in-gabon-western-africa/ https://blogs.scientificamerican.com/guest-blog/natures-nucl...
- hermitdev 7y agoIIRC, it was somewhere around the India/Pakistan border. Ive seen the episode, but its been a while.
- ColanR 7y agoI remember reading about that on wikipedia years ago. Don't remember the name, but it's the site of a large crater, and I think there was also glass in the area similar to what's created by modern nuclear explosions.

- wbl 7y agoThat's only one half life of plutonium-244, a small amount of which would be present in spent fuel.
- marcosdumay 7y agoPlutonium is not spread worldwide. The stuff that spreads has shorter half-life.
- zaphirplane 7y agoWhat about fossils, surely children in that ancient vibrant civilization dropped their shoes, phone, remote and it got fossilized
- marcosdumay 7y agoThe article explains that one. If we were gone today, we would probably not leave any fossil.
