For his work, Libby received the Nobel Prize in Chemistry in 1960.
Perhaps with proper use of this powerful tool we can learn about the past and look to the future.

A fluorescence event is proportional to the decay event of C14; and the frequency is proportional to the number of C14 atoms in the sample.
Instead of measuring the radioactivity of the sample (as in LCS); Accelerator Mass Spectrometry (AMS) counts directly the radiocarbon atoms.
As you can see, the range is quite substantial for some calendar years.
