Carbon 14 bomb pulse dating interacail dating
Forensic experts use radiocarbon dating to establish if an individual died recently (perhaps a matter for the Justice Department) or in antiquity (a matter for the archaeologist). Living things assimilate radiocarbon from the atmosphere.
AD 1963 marked the signing of the Partial Test Ban Treaty (PTBT) by the United States, United Kingdom, and the Soviet Union wherein it was agreed that nuclear weapons testing would no longer be performed above ground surface.
“A geopolitical phenomenon—this Cold War bomb testing—has, in a way, put a date stamp on everything and everybody,” Spalding says.
The bomb pulse has been declining since the 1963 above-ground test ban treaty, creating a sort of clock they could exploit.
Additionally, using the radiocarbon signature within trabecular bone vs cortical bone has been cited as a means of identifying which side of the bomb curve the individual lived (prior to 1963 or post 1963). You only need to include the confirmation code in the package.
