Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).

The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more than 50,000 years old.

Carbon dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized.

These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio.Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.Other methods scientists use include counting rock layers and tree rings.These isotopes have longer half-lives and so are found in greater abundance in older fossils.Some of these other isotopes include: back to the last global catastrophe (i.e.
