Radioactive dating work

This restriction extends to animals that consume seafood in their diet.As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.This human nuclear activity will make precise dating of fossils from our lifetime very difficult due to contamination of the normal radioisotope composition of the earth with addition artificially produced radioactive atoms.

electrons and protons) and turn from one element into another.

These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.

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.

Other methods scientists use include counting rock layers and tree rings.

When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.
