Radiocarbon dating by accelerator mass spectrometry

As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.

The rate at which C atoms, half of them will decay in 5730 years.

Since this rate is slow relative to the movement of carbon through food chains (from plants to animals to bacteria) all carbon in biomass at earth's surface contains atmospheric levels of C is present at atmospheric levels, the molecule must derive from a recent plant product.

Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis.

The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. The pre-accelerated ions are usually separated by a first mass spectrometer of sector-field type and enter an electrostatic "tandem accelerator".

This is a large nuclear particle accelerator based on the principle of a Tandem van de Graaff Accelerator operating at 0.2 to many million volts with two stages operating in tandem to accelerate the particles.

Mickiewicz University in Poznan The Laboratory is kept by the Foundation of the A.

Mickiewicz University and is housed in the area of the Poznan Park of Science and Technology C laboratories are usually open to cooperate with wide community.

Poznan Radiocarbon Laboratory is the first such institution in the Central-Eastern Europe.

Performance of the Poznan Radiocarbon Laboratory (PRL) is possible due to a close collaboration with the AMS Laboratory (LAMS), housed at the same floor, and leaded by the same person.

Signals of this kind are often used by chemists studying natural environments.
