How Carbon Dating works Carbon dating is one method scientists use to measure the ages of objects which were alive at some time in the past.

In our atmosphere there are particles of carbon, when rays from the sun hit them it turns a few of them into carbon 14 (a radioactive carbon).

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

Co­smic rays enter the earth's atmosphere in large numbers every day.

For example, every person is hit by about half a million cosmic rays every hour.

Carbon-14 is considered to be a highly reliable dating technique.

The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

This restriction extends to animals that consume seafood in their diet.

This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.
