Part of the result of these collisions is the production of radiocarbon (C, pronounced "c fourteen"), carbon atoms which are chemically the same as stable carbon, but have two extra neutrons.
Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms.
The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Radiocarbon dating is based on a few relatively simple principles. The vast majority of these are C (pronounced "c twelve"), the stable isotope of carbon.
However, cosmic radiation constantly collides with atoms in the upper atmosphere.
When an organism dies (whether plant or animal) its intake of carbon atoms ceases.
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.Thus, the ratio of radiocarbon to stable carbon in a living plant is the same as the ratio of radiocarbon to stable carbon in the atmosphere at any given time.Animals (and humans) get their carbon atoms primarily from what they eat (i.e., plants).The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.
Radiocarbon dating works by precisely measuring the ratio of radiocarbon to stable carbon in a sample. The tree-ring chronologies have been constructed by counting the annual rings in living trees and matching patterns in these rings to older wood and dead trees.
