How Does Radiocarbon Dating Work? - Instant Egghead #28. However, the principle of carbon-14 dating applies to other isotopes as well. How do scientists determine the age of fossils that have been under the surface of the earth forthousands of
How Carbon-14 Dating Works HowStuffWorks By looking at the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely. So, if you had a fossil that had 10 percent carbon-14 compared to a living sample, then that fossil would be: t = [ ln (0.10) / (-0.693) ] x 5,700 years t = [ (-2.303) / (-0.693) ] x 5,700 years t = [ 3.323 ] x 5,700 years Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old. Carbon-14 dating is something that you hear about in the news all the time. Find out how carbon-14dating works and why carbon-14 dating is so accurate!
How Carbon-14 Dating Works The new isotope is ed "radiocarbon" because it is radioactive, though it is not dangerous. Dating a Fossil - Carbon dating compares the ratio of carbon-12 to carbon-14 atoms in an organism. Learn about carbon dating and find out what the carbon-14 half-life is.
