Carbon dating test meaning

Sometimes carbon dating will agree with other evolutionary methods of age estimation, which is great. Equilibrium is the name given to the point when the rate of carbon production and carbon decay are equal. This half-life is very constant and will continue at the same rate forever.

By testing the amount of carbon stored in an object, and comparing to the original amount of carbon believed to have been stored at the time of death, scientists can estimate its age. At this point, the carbon dating data is simply disregarded. Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate. Definition of Carbon Dating Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. They attempted to account for this by setting as a standard year for the ratio of C to C, and measuring subsequent findings against that.

For example, recently science teams at the British Antarctic Survey and Reading University unearthed the discovery that samples of moss could be brought back to life after being frozen in ice. Most concerning, though, is when the carbon dating directly opposes or contradicts other estimates. Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached.

Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands. Radioactive Half-Lives Each radioactive isotope decays by a fixed amount, and this amount is called the half-life.
