As we mentioned above, the carbon-14 to carbon-12 ratio in the atmosphere remains nearly constant. A special kind of radiocarbon dating: Bomb radiocarbon dating. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13. Ethan Siegel / Simon Swordy/ nasa. The House from Nowhere, arthur. The Cosmic Story of Carbon-14, ethan Siegel writes: The only major fluctuation in carbon-14 we know of occurred when we began detonating nuclear weapons in the open air, back in the mid-20th Century. Cosmic rays high energy particles from beyond the solar system bombard Earths upper atmosphere continually, in the process creating the unstable carbon-14. A method of establishing the approximate age of carbonaceous materials, such as fossil remains or archaeological specimens, by measuring the amount of radioactive carbon-14 remaining in them also carbon-14 dating. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age Also called carbon-14 dating. A carbon atom is a carbon atom is a carbon atom. Because the cosmic ray bombardment is fairly constant, theres a near-constant level of carbon-14 to carbon-12 ratio in Earths atmosphere.

Aboveground nuclear testing almost doubled the amount of carbon-14 in the atmosphere. By in Earth Human World, cosmic rays bombard Earths atmosphere, creating the unstable isotope carbon-14. They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks. This isotope lets scientists learn the ages of once-living things. The unstable carbon-14 gradually decays to carbon-12 at a steady rate. An isotope is what scientists call two or more forms of the same element. This plot shows the level of carbon-14 in the atmosphere as measured in New Zealand (red) and Austria (green representing the Northern and Southern Hemispheres, respectively. Most carbon consists of the isotopes carbon 12 and carbon 13, which are very stable. Carbon 14 has a half-life of 5,780 years, and is continuously created in Earth's atmosphere through the interaction of nitrogen and gamma rays from outer space.
