Cosmic rays that enter our atmosphere from outer space strike the earth and transform regular nitrogen (nitrogen 14) to radioactive carbon (carbon 14).Willard Libby and his associates discovered carbon 14 (C 14) as a method for the dating of earlier organic materials.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.Request low-res file 530 pixels on longest edge, unwatermarked Request/Download high-res file Uncompressed file size: 28.3MB Downloadable file size: 2.0MB Price image Please login to use the price calculator Credit: JACK FIELDS/SCIENCE PHOTO LIBRARY Caption: Chemist, Dr. Willard Libby (1908-1980), is known for his development of radiocarbon or Carbon 14 dating. Libby also worked as a member of the Manhattan Project before winning the Nobel prize in Chemistry in 1960.
There are three forms of carbon that naturally occur forming the building blocks of all plant and animal life.But later research revealed that its inaccuracy increases in accordance with the actual age of the material (*C. Reed,“Animal Domestication in the Prehistoric Near East,” in Science, 130, 1959, p.1630; University of California at Los Angeles, “On the Accuracy of Radiocarbon Dates,”in Geochronicle, 2, 1966 [Libby’s own laboratory]). This method of dating is called carbon-14 dating, C-14 dating, or radiocarbon dating.Korff predicted that the reaction between these neutrons and nitrogen-14, which predominates in the atmosphere, would produce carbon-14, also called radiocarbon.Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.The stable C12 and C13, and the unstable or radioactive Carbon 14. Only one C14 atom exists for every one trillion C12 atoms.
