Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. All these methods are based on the fact the rate at which radioactive nuclei disintegrate is unaffected by their environment, it can be used to estimate the age of any material sample or object which contains a radioactive isotope. Calculations of the decay of radioactive nuclei are relatively straightforward, owing to the fact that there is only one fundamental law governing all decay process. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time.

A man and meet a good man. If a scientist were to compute this, he or she would say two half-lives went by at a rate of 4. That's a lot of years. So you see, earth scientists are able to use the half-lives of isotopes to date materials back to thousands, millions, and even to billions of years old. The half-life is so predictable that it is also referred to as an atomic clock.
Since all living things contain carbon, carbon is a common radioisotope used primarily to date items that were once living. Carbon has a half-life of approximately 5, years and produces the decay product nitrogen Just as in the example with uranium, scientists are able to determine the age of a sample by using the ratios of the daughter product compared to the parent.
Also, when dating with carbon, scientists compare the amount of carbon to carbon These are both isotopes of the element carbon present in a constant ratio while an organism is living; however, once an organism dies, the ratio of carbon decreases as the isotope deteriorates. Radiocarbon dating can only be used to date items back to as far as about 50, years old. Radiocarbon dating was used to identify a forged painting based upon the concentrations of carbon detected on the canvas within the atmosphere at the time that the picture was painted.
So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives. An isotope is a variation of an element based upon the number of neutrons. The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity. An isotope disintegrates at a constant rate called the half-lifeor the time it takes for half the atoms of a sample to decay.
The half-life can also be termed an atomic clock. By counting the number of half-lives and the percentages remaining of parent and daughter isotopes, scientists are able to determine what they call the absolute age of a discovery.
