Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Histories of archaeology often refer to its impact as the radiocarbon revolution.
How do you use radiocarbon dating in a sentence?
The eruption was dated by corrected radiocarbon dating. Some inventors were able to develop a time machine which uses some kind of radiocarbon dating. Radiocarbon dating indicated that the human remains were about 10,000 years old. The radiocarbon dating concluded that the rag paper could date between 1475 and 1640.
What is meant by radiocarbon dating?
Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.
Which best defines radiocarbon dating?
noun. a technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14 C acquired from the atmosphere when they formed part of a living plant. The 14 C decays to the nitrogen isotope 14 N with a half-life of 5730 years.
