Originally published in Creation 14, no 2 March So slick and convincing are the presentations of results, particularly in glossy media and museum propaganda, that no one even bothers to question how these dating methods work, what assumptions are involved, and how reliable they are.
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. 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. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample. It is founded on unprovable assumptions such as 1 there has been no contamination and 2 the decay rate has remained constant. However, to read any clock accurately we must know where the clock was set at the beginning. Most people think that radioactive dating has proven the earth is billions of years old.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon 14 C , a radioactive isotope of carbon. The method was developed by Willard Libby in the late s and soon became a standard tool for archaeologists. Libby received the Nobel Prize in Chemistry for his work in The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay.
H ow old is planet Earth? There are enormous differences of opinion. The most common view is that Earth is approximately 4. The lowest age what is radioactive dating method on a scientific basis is in the 6 to 10 thousand year range. Theoretically, Creationism remains workable within a wide range of age estimates.
