Half life of carbon dating

The carbon-14 undergoes radioactive decay once the plant or animal dies, and measuring the amount of carbon-14 in a sample conveys information about when the plant or animal died.

Perhaps the most widely used evidence for the theory of evolution through natural selection is the fossil record.

With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

This technique relies on the property of half-life.Let's say you found a fossil you think to be a human skeleton.The best radioactive element to use to date human fossils is Carbon-14.There are several reasons why, but the main reasons is that Carbon-14 is a naturally occurring isotope in all forms of life and its half-life is about 5730 years, so we are able to use it to date more "recent" forms of life relative to the geologic time scale.You would need to have access to scientific instruments at this point that could measure the amount of radioactivity in the sample, so off to the lab we go!

Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope.

One thought on “half life of carbon dating”

  1. Sometimes the dialogue appears goofy in Booty Calls but those aspects are sometimes the perfect portrayal of real-life dating; the racy, hysterical, and outright vulgar chaos that ensues when someone is amid a sex-frenzy.
