Carbon dating for dummies
In fact, research has been conducted which suggests that nuclear tests may have doubled the concentration of C-14 in this time, compared to natural production by cosmic rays.

Nevertheless, it remains the most accurate means of dating the scientific community has discovered so far. We’ve also recorded an entire episode of Astronomy Cast all about How Carbon Dating Works.
It is naturally radioactive and unstable, and will therefore spontaneously decay back into N-14 over a period of time.
This property makes it especially useful in a process known as “radiocarbon dating”, or carbon dating for short.
Because the radiocarbon is radioactive, it will slowly decay away.

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.
