What is the meaning of radiometric dating

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or .. isotopes were produced by nucleosynthesis in supernovas, meaning that any parent isotope with a short half-life should be extinct by now.

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-life , or 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.
