Theoretically how does carbon-dating work
Webb11 aug. 2024 · The main doubt is how carbon dating works as the process is used to identify the date of the sample that discharges carbon dioxide into the environment. Later the chemist discovered the method that identifies the radioactivity of carbon-14, the most used isotope in carbon dating. 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. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon ( C) is constantly being created in the Earth's atmosphere by t…
