Seldom has a single discovery generated such wide public interest.” Libby’s research demonstrated the usefulness of carbon-14 in dating samples thousands of years old.Though radiocarbon dating clearly enjoys “wide public interest,” it also generates much confusion and discord among Christians, which leads to an obvious question: is Libby’s celebrated work a reliable technique for dating ancient objects?Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.The short answer is a resounding YES and here’s why.The concept behind radiocarbon dating is rather simple.Once an organism dies, it stops taking in carbon-14.

The most well-known of all the radiometric dating methods is radiocarbon dating.After radiocarbon forms, the nuclei of the carbon-14 atoms are unstable, so over time they progressively decay back to nuclei of stable nitrogen-14.3 A neutron breaks down to a proton and an electron, and the electron is ejected. The ejected electrons are called beta particles and make up what is called beta radiation. Different carbon-14 atoms revert to nitrogen-14 at different times, which explains why radioactive decay is considered a random process.In the presentation speech for the 1960 Nobel Prize in Chemistry, one scientist described the work by honoree Willard Libby with these words: “Seldom has a single discovery in chemistry had such an impact on the thinking of so many fields of human endeavour.Although many people think radiocarbon is used to date rocks, it is limited to dating things that contain carbon and were once alive (fossils).Radiocarbon (carbon-14 or C) forms continually today in the earth’s upper atmosphere.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.
