Half life and radiocarbon dating duggar boys dating

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.For radiocarbon dating to be possible, the material must once have been part of a living organism.This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).

Plant eating animals (herbivores and omnivores) get their carbon by eating plants.

All animals in the food chain, including carnivores, get their carbon indirectly from plant material, even if it is by eating animals which themselves eat plants.

The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.

Once an organism dies the carbon is no longer replaced.

Because the radiocarbon is radioactive, it will slowly decay away.
