Radio Carbon dating

Radiocarbon dating is a scientific method used to determine the age of an object containing organic material by measuring the amount of carbon-14 it contains. Carbon-14 is a radioactive isotope of carbon that is formed in the atmosphere through cosmic radiation. Living organisms absorb carbon, including carbon-14, during their lifetime. Once the organism dies, it no longer absorbs carbon, ______ ______ _______ ____ __________ _______ _______.
