Carbon-14 is also passed onto the animals that eat those plants.

After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

DR CHRISTINE PRIOR In conventional radiocarbon dating, you’re measuring the presence of the C-14 when you measure the radioactive decay.

The C-14 decays with the beta particle, and you have some detection equipment and you count the C-14s one by one.

Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.

Martian meteorites - containing organic material thought to be proof of life on Mars - were also taken to the machine and proved to be mostly matter from Earth.

Most of the funding for the machine - which was built to supplement the aging machine built in 1981 - came from the National Science Foundation, with the UA contributing about a third.

Dr Christine Prior is Team Leader of the Rafter Radiocarbon Laboratory at GNS Science.

In this video, she compares conventional and accelerator mass spectrometry (AMS) radiocarbon dating.

Love-hungry teenagers and archaeologists agree: dating is hard.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.

Though still heavily used, relative dating is now augmented by several modern dating techniques.
