For his contributions to the team that developed this process, Libby was awarded the Nobel Prize in Chemistry in 1960.
The SAM Laboratories therefore had to find a way of separating kilograms of it from the more abundant uranium-238.
Gaseous diffusion worked on the principle that a lighter gas diffuses through a barrier faster than a heavier one at a rate inversely proportional to its molecular weight.
When objects of the Old Kingdom and Middle Kingdom of Egypt yielded carbon dates that appeared roughly comparable with the historical dates, Libby made his method known.
First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century.
In 1950, he became a member of the General Advisory Committee (GAC) of the Atomic Energy Commission (AEC).
He was appointed a commissioner in 1954, becoming its sole scientist.
