All objects that have the [infopopup: Carbon is in all [infopopup: The carbon level of the object is then measured by scientists. It is good for dating for the last 50, years to about years ago and can create chronologies for areas that previously lacked calendars.
InAmerican chemist Willard Libby, who worked on the development of the atomic bomb, published the first set of radiocarbon dates. His radiocarbon dating technique is the most important development in absolute dating in archaeology and remains the main tool for dating the past 50, years. Carbon has 3 isotopic forms: Carbon, Carbon, and Carbon The numbers refer to the atomic weight, so Carbon has 6 protons and 6 neutrons, Carbon has 6 protons and 7 neutrons, and Carbon has 6 protons and 8 neutrons.

Radiocarbon is produced in the upper atmosphere after Nitrogen isotopes have been impacted by cosmic radiation. Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.
So every living thing has a certain amount of radiocarbon within them. After an organism dies, the radiocarbon decreases through a regular pattern of decay. This is called the half-life of the isotope.
