Does radiation affect carbon dating questions to ask before dating someone

The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960.Even with these weird––and challenging from an old-earth perspective––results, radiocarbon (or, carbon-14) dating remains one of the best tools for determining the ages of things that lived from 500 to 50,000 years ago. Carbon-14 (C) is a naturally occurring radioisotope of carbon and is found in trace amounts on Earth.It is produced in Earth’s atmosphere as cosmic rays hit nitrogen molecules and is then absorbed from the air by plants, which then pass it on to animals in the food chain.

After ten half-lives (or 57,300 years), less than one-thousandth of the original amount remains.

Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.

When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.

Carbon-14 decays to nitrogen-14 by emitting an electron and a neutrino, and it does so with a half-life of 5,730 years.

Thus, if one started with 1,024 atoms of carbon-14, after 5,730 years, only 512 would remain.
