Once you understand the basic science of radiometric dating, you can see how wrong assumptions lead to incorrect dates. How Carbon- 1. 4 Dating Works . A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,0. How do scientists know how old an object or human remains are? 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- 1. Carbon- 1. 4 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 5. 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. Radiocarbon dating uses carbon isotopes. Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two. Radiocarbon dating. Radiocarbon or Carbon-14 dating is a technique used by scientist to date bones, wood, paper and cloth. Carbon-14 is a radioisotope of Carbon. How does radiocarbon dating work? All plants and animals on Earth are made principally of carbon. During the period of a plant's life, the plant is taking in carbon. Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively.
