Gas proportional counting in carbon dating

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.The Miami-based lab provides unlimited technical support throughout the process.

The minimum sample requirements for AMS dating are significantly smaller than for radiometric dating techniques, allowing even a few milligrams of sample to be dated for certain sample types.

Liquid scintillation counting involves converting the sample into a carbon-rich liquid, which is then added to a scintillator.

When beta particles are emitted, the scintillator will emit a flash of light.

All samples submitted for radiocarbon dating are measured by AMS. You only need to include the confirmation code in the packag​e​​.

The ISO 17025-accredited lab’s standard AMS dating service reports results within 14 business days, with faster services also available. Read about sample material return To provide you with the best possible user experience, this website uses cookies.

There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry.
