A new, more stable isotope, called the decay, or daughter product, takes its place.

Radiocarbon dating was used to identify a forged painting based upon the concentrations of carbon-14 detected on the canvas within the atmosphere at the time that the picture was painted.

So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives.

Just as in the example with uranium, scientists are able to determine the age of a sample by using the ratios of the daughter product compared to the parent.

Also, when dating with carbon-14, scientists compare the amount of carbon-14 to carbon-12.

Since all living things contain carbon, carbon-14 is a common radioisotope used primarily to date items that were once living.

Carbon-14 has a half-life of approximately 5,730 years and produces the decay product nitrogen-14.As a member, you'll also get unlimited access to over 70,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.If a scientist were to compute this, he or she would say two half-lives went by at a rate of 4.5 billion years per half-life; therefore, the sample is approximately 2 times 4.5 billion, or 9 billion years old. So you see, earth scientists are able to use the half-lives of isotopes to date materials back to thousands, millions, and even to billions of years old.The half-life is so predictable that it is also referred to as an atomic clock.Free 5-day trial Ever wonder how scientists concluded the age of the earth to be about 4.6 billion years old or how geologists determined the ages of caverns, rocks, volcanoes, the Himalayas, or even the age of Pompeii bread?
