Uses and application of radiation in radioactive dating
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).Dating Not the saucy kind of dating: Richard was reportedly “not shaped for sportive tricks, nor made to court an amorous looking glass”.The ages of things of interest to archaeologists – including royal bones – can be estimated from the proportion of carbon-14 they contain.The most common of these medical procedures involve the use of x-rays — a type of radiation that can pass through our skin.When x-rayed, our bones and other structures cast shadows because they are denser than our skin, and those shadows can be detected on photographic film.
As a result, medical procedures using radiation have saved thousands of lives through the detection and treatment of conditions ranging from hyperthyroidism to bone cancer.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.Geological Time | Geologic Time Scale | Plate Tectonics | Radiometric Dating | Deep Time | Geological History of New Zealand | Radiometric Dating Radiometric measurements of time Since the early twentieth century scientists have found ways to accurately measure geological time.The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
