The new machine is an addition to an older machine, built in 1981, that has been used by scientists to date the Shroud of Turin, once thought to be the burial cloth of Jesus.
Doug Donahue, a UA professor emeritus of physics, has analyzed many of the samples and said that theory was discredited ,and it was proved that the cloth was from the Middle Ages.
In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.
Radiocarbon dating is a method of estimating the age of organic material.
Donahue said the machine has been used for several things - from helping to predict weather patterns such as El Nio to verifying the authenticity of paintings. Dana Biddulph, a physics graduate student who has been working with the machine, said about 5,000 samples are analyzed a year for various disciplines all over the world.
Biddulph said the newer machine is being used to date the Dead Sea Scrolls - a collection of written scrolls found in the 1940s - and is confirming estimates that they are about 2,000 years old.
Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
