Radiocarbon dating by accelerator mass spectrometry

Therefore, communication between PRL and LAMS is fast and effective.Organisation of Laboratory is an effect of cooperation of the Adam Mickiewicz University, Institute of Archaeology and Ethnology, Polish Academy of Sciences, and Centre for Archaeological Research, Foundation of the A.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.

All carbon atoms have a nucleus containing six protons.

Isotopes participate in the same chemical reactions but often at differing rates.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

Thanks to the high energy of the ions, these can be separated by methods borrowed from nuclear physics, like degrader foils and gas-filled magnets. Purser and colleagues also published the successful detection of radiocarbon using their tandem at Rochester.

Individual ions are finally detected by single-ion counting (with silicon surface-barrier detectors, ionization chambers, and/or time-of-flight telescopes). Soon afterwards the Berkeley and French teams reported the successful detection of Be, an isotope widely used in geology.

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