Precisely dating archaeological artifacts is not as easy or harmless as it might seem.

The most common method, radiocarbon dating, requires that a piece of an organic object be destroyedwashed with a strong acid and base at high temperature to remove impurities, and then set aflame.

“The word groundbreaking is used so often that it sometimes has lost its meaning but in today’s event, it is marking a development, the development of radiocarbon dating, [for which] the word groundbreaking is both appropriate and non-hyperbolic,” said Diermeier.

Relative dating stems from the idea that something is younger or older relative to something else.A professor’s discovery of radiocarbon dating in 1946 was designated as a National Historic Chemical Landmark on Monday.The dedication took place at Kent Chemical Laboratory, the building in which professor Willard F.N through β emission, the isotope has a very long half life (later found to be 5730 years).

This opened up new possibilities for using radioactive tracers to elucidate reaction mechanisms.This method had a tremendous impact on archaeology, as it allows to accurately date artifacts from a large timescale. He joined UC Berkeley's Radiation Laboratory, working with Sam Ruben.
