Using this finding Willard Libby and his team at the University of Chicago proposed that Carbon was unstable and underwent a total of 14 disintegrations per minute per gram. Not all materials can be radiocarbon dated. Dates on organic material recovered from strata of interest can be used to correlate strata in different locations that appear to be similar on geological grounds.
