Simple definition of carbon dating

This is why radiocarbon dating is only useful for dating objects up to around 50,000 years old (about 10 half-lives).

Radioactive carbon-14 is continually formed in the atmosphere by the bombardment of cosmic ray neutrons on nitrogen-14 atoms.

the 14 biological objects from archaeological excavations of the tram line 2, with particle accelerators, AMS method, including the bone material, burnt or not, with or without extraction of collagen.

This technique works well for materials up to around 50,000 years old.

The technique used is called carbon dating, and in this lesson we will learn what this is and how it is used. Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. In the late 1940s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon-14, a radioactive isotope.

Libby was awarded the Nobel Prize in chemistry for his work in 1960.

After it forms, carbon-14 naturally decomposes, with a half-life of 5,730 years, through beta-particle decay.

For the record, a beta-particle is a specific type of nuclear decay. Image 1 shows carbon-14 production by high energy neutrons hitting nitrogen-14 atoms, while in Image 2, carbon-14 naturally decomposes through beta-particle production.
