Radiocarbon dating may only be used on organic materials.
Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.
The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study of the sequence of the evolution of fossils.
Scientists use isotopes of carbon, carbon-13 and carbon-14, to study the age of organic material.
The unstable Carbon within the organism begins to decay to form Nitrogen by emitting a beta particle.

So a lot of that decline you’re going to see in lake sediment in recent times is not because the lakes are getting cleaner, it’s just the illusion of all this carbon-13 being diluted out in the atmosphere.
MF: Because it’s diluted by this massive amount of the other carbon.
And if you have a lake with lots of pollutants that make really thick, scummy algae blooms, the algae usually have lots of this carbon-13 in them.
MF: And you would conclude, great, hey, the lake is getting better.
