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.
Because of the carbon cycle, there is always carbon-14 present in both the air and in living organisms.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.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.
You might remember that it was mentioned earlier that the amount of carbon-14 in living things is the same as the atmosphere.
