After viewing the video on carbon dating, use your newfound knowledge to: Did you know…

We have over 95 college courses that prepare you to earn credit by exam that is accepted by over 2,000 colleges and universities.

Once the organism dies, the amount of carbon-14 reduces by the fixed half-life - or the time required for half of the original sample of radioactive nuclei to decay - of 5,730 years, and can be measured by scientists for up to 10 half-lives.

Measuring the amount of radioactive carbon-14 remaining makes it possible to work out how old the artifact is, whether it's a fossilized skeleton or a magnificent piece of artwork.

You can test out of the first two years of college and save thousands off your degree.

Anyone can earn credit-by-exam regardless of age or education level.

Radioactive carbon-14 is continually formed in the atmosphere by the bombardment of cosmic ray neutrons on nitrogen-14 atoms.

After it forms, carbon-14 naturally decomposes, with a half-life of 5,730 years, through beta-particle decay.

For example, if you start off with 1000 radioactive nuclei with a half-life of 10 days, you would have 500 left after 10 days; you would have 250 left after 20 days (2 half-lives); and so on.

It is often used on valuable artwork to confirm authenticity.

For example, look at this image of the opening of King Tutankhamen's tomb near Luxor, Egypt during the 1920s.

Radiocarbon dating has been used extensively since its discovery.

Examples of use include analyzing charcoal from prehistoric caves, ancient linen and wood, and mummified remains.
