What is measured in the radiocarbon dating of organic materials?

the increase of carbon-12 in a living organism

the ratio of carbon-12 to carbon-14 in a sample

the ratio of carbon-14 to carbon-12 in a sample

the decrease in carbon-12 in a decaying organism

1 answer

In radiocarbon dating of organic materials, what is measured is the ratio of carbon-14 to carbon-12 in a sample. This method allows scientists to determine the age of an object containing organic material by measuring the remaining amount of carbon-14, which decays over time after the organism has died.
