An isotope disintegrates at a constant rate called the half-life, or the time it takes for half the atoms of a sample to decay. By counting the number of half-lives and the percentages remaining of parent and daughter isotopes, scientists are able to determine what they call the absolute age of a discovery.

Carbon-14 is a specific isotope used in dating materials that were once living.

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?

Well, scientists are able to answer all of these wondrous questions and more by use of a process called radiometric, or radioactive, dating.

When scientists find a sample, they measure the amount of the original, or parent, isotope and compare it to the amount of the decay product formed.

They then count the number of half-lives passed and compute the absolute age of the sample.

These are both isotopes of the element carbon present in a constant ratio while an organism is living; however, once an organism dies, the ratio of carbon-14 decreases as the isotope deteriorates.

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.

Other common isotopes used in radioactive dating are uranium, potassium, and iodine. We have over 160 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.
