Carbon 14 is used for radio dating of organic materials Xdating sex
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 50,000 years old.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

This restriction extends to animals that consume seafood in their diet.
As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.
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).
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
It was developed right after World War II by Willard F.
Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.
Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.
Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.
The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old.
