Radiocarbon dating ams

The radiocarbon dating laboratory at the Center for Applied Isotope Studies was founded in 1968 and was originally called the Geochronology Laboratory of the University of Georgia.CAIS is the oldest ISO/IEC 17005 accredited radiocarbon laboratory in the world.The measurement of radiocarbon by mass spectrometry is very difficult because its concentration is less than one atom in 1,000,000,000,000.The accelerator is used to help remove ions that might be confused with radiocarbon before the final detection.

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

AMS, on the other hand, can in principle detect a much higher proportion (typically about 1% of the total) allowing sample sizes to be smaller by a factor of about a thousand.

The method is relatively new because it needs very complicated instruments first developed for Nuclear Physics research in the late 20th century.

In common with other kinds of mass spectrometry, AMS is performed by converting the atoms in the sample into a beam of fast moving ions (charged atoms).

The mass of these ions is then measured by the application of magnetic and electric fields.

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