Final answer:
Radioactive dating is a method of measuring the age of an object or event by determining the ratio of a radioactive isotope to its stable decay product. Carbon-14 dating is an example of radioactive dating used to determine the age of organic artifacts.
Step-by-step explanation:
Radioactive dating is a method of measuring the age of an object or event using the concept of half-life. Half-life is the time it takes for half of a radioactive substance to decay. By measuring the ratio of the radioactive isotope to its stable decay product, scientists can determine the age of the object or event. For example, carbon-14 dating measures the ratio of carbon-14 to carbon-12 to determine the age of organic artifacts.
