A report about the new method was published online July 1 in Proceedings of the National Academy of Sciences.Fisher studies mammoths and mastodons, and over several decades has developed techniques to interpret the life histories of those prehistoric pachyderms by analyzing growth layers within their tusks."This could be used in specific cases of ivory seizures to determine when the ivory was obtained and thus whether it is legal," said University of Utah geochemist Thure Cerling, senior author of the study.U-M paleontologist Daniel Fisher worked with Cerling and a former University of Utah researcher, Kevin Uno, on the project.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.

How do scientists know how old an object or human remains are?If you look carefully at the half-lives of isotopes in the Uranium series you appreciate that the Uranium has a much longer half-life than any of the others. During its lifetime a biological entity (plant or animal) takes an active part in the carbon cycle and it contains the same proportion of the isotope as the atmosphere does (about one ten millionth of the carbon is carbon-14).Sterilisation of Food and Surgical Instruments Gamma rays kill bacteria.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
