Sediment plutonium dating

Over 60 further radionuclides are detectable in nature, either as daughters of these, or through natural production on Earth by cosmic radiation.

The range of the half-lives of radioactive atoms have no known limits and span a time range of over 55 orders of magnitude.

Radionuclides occur naturally and are artificially produced in nuclear reactors, cyclotrons, particle accelerators or radionuclide generators.

And these skeletons are thousands of years old, even by traditional archaeological standards. Why did the bodies not decay or get eaten by wild animals?

Furthermore, there is no apparent cause of a physically violent death.

reached the street level, they discovered skeletons scattered about the cities, many holding hands and sprawling in the streets as if some instant, horrible doom had taken place.

People were just lying, unburied, in the streets of the city.

Slon and Meyer are not the first to decode ancient dirt.

Palaeogeneticist Eske Willerslev of the Natural History Museum of Denmark in Copenhagen pioneered the approach in 2003, to find out about the plants and animals that populated prehistoric environments.

The technique opens up a new way to probe prehistory.
