Can a pulse of radioactive carbon stamp a date on life?

A pulse of radioactive carbon released by nuclear bomb testing stamped a date on every living cell, giving scientists the opportunity of a lifetime. Aboveground nuclear bomb tests, like this French test over Fangataufa Atoll, created a pulse of radioactive carbon in the atmosphere.

What is radiocarbon dating?

Traditionally, radiocarbon dating has been considered to be an archeological tool rather than a forensic one. Radiocarbon or carbon-14 ( 14 C) is produced naturally in the atmosphere by cosmic ray interactions with nitrogen.

How do we date bomb pulses?

The premise of bomb pulse dating is fairly straightforward. Most aboveground nuclear bomb testing happened between 1955 and 1963, and those detonations released untold numbers of neutrons into the atmosphere. These slammed into nitrogen atoms, causing their nuclei to eject a proton. What was once a seven-proton nitrogen became a six-proton carbon.
