Over the years, other secondary radiocarbon standards have been made.

Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis.

Accelerator mass spectrometry (AMS) is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample.

In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present. Some inorganic matter, like a shell’s aragonite component, can also be dated as long as the mineral’s formation involved assimilation of carbon 14 in equilibrium with the atmosphere.

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.

These values have been derived through statistical means.

By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.

The equation governing the decay of a radioactive isotope is. The carbon is of geological origin and has no detectable 14 C, so the 14 C / 12… continue reading »
