The ratio of carbon to carbon carbon dating example calculation the moment of death is the same as every other living thing, carbon dating example calculation the carbon decays calcullation is not replaced. The carbon decays with its half-life of 5, years, while the amount of carbon remains constant in the sample.
By looking at the ratio of carbon to carbon in the sample and comparing it to the ratio in a living organism, it is possible to carbon dating example calculation the age of a formerly living thing fairly precisely. So, if you had a fossil that had 10 percent carbon compared to a living sample, then that fossil would be:. Because the half-life of carbon is 5, years, it is only reliable for dating objects up to about 60, years old.
However, the principle of carbon dating applies to other isotopes as well. Potassium is another radioactive element naturally found in your body and has a half-life of 1. The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy. However, radioisotope dating may not work so well in the future.
