After a creature's death the isotope would slowly decay away over millennia at a fixed rate.Thus the less of it that remained in an object, in proportion to normal carbon, the older the object was.

Raw (i.e., uncalibrated) radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), with "present" defined as CE 1950.Such raw ages can be calibrated to give calendar dates.Carbon dating uses an unstable isotope of carbon to find the date of dead substances.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.But underlying all of that is a body of scientific work and assumptions that you’ve conveniently ignored in the interest of “character driven plot”. The atomic fragments of this are still energetic to have a half dozen more of these collisions.

But I have news for you: your characters and your plot make less sense when you take these shortcuts. This is what is known as the “cosmic ray air shower”.

Carbon-14 only works for things between 3 and 40 thousand years old. Carbon dating is based on an isotope of carbon, carbon 14, that's unstable. We breathe in carbon dioxide, we eat carbon, we take in carbon and so our bodies continually renewing our supply of carbon 14.

It decays with a half life of 5700 years into nitrogen 14 and electron and an electron antineutreno. So for that reason, every living thing that is interacting with its environment is expected to have this natural abundance of carbon 14. But when something dies, now it's not interacting with the environment anymore. We know that the amount at time t is equal to the initial amount times one half to the time over the half life, alright?

The prodigious mobilization of science that produced nuclear weapons was so far-reaching that it revolutionized even the study of ancient climates.

Nuclear laboratories, awash with funds and prestige, spun off the discovery of an amazing new technique — radiocarbon dating.

There are also trace amounts of the unstable radioisotope carbon-14 (14C) on Earth.
