List a range of items that can be dated by isotope carbon 14?

Answer 1

Sure, honey. Carbon 14 can be used to date organic materials like wood, charcoal, bone, and shell. So if you're trying to figure out the age of that old wooden artifact or a fossilized bone, carbon 14 is your go-to method. Just remember, not everything can be dated with this technique, so don't go trying to carbon date your grandma's antique vase.

Answer 2

Oh, dude, like, you can totally date organic stuff with carbon 14, you know? So, we're talking about things like wood, charcoal, bones, and shells. Basically, anything that used to be alive and now it's all, like, decomposed and stuff.

Answer 3

Organic materials such as wood, cloth, bone, and shells, as well as remains of once-living organisms like fossils or ancient human artifacts, can be dated using carbon-14 isotopes. Agricultural residues, peat, and sediment layers can also be dated accurately using carbon-14.

Answer 4

It is not that simple. Carbon 14 (C14) is created in the upper atmosphere by the action of cosmic rays on Nitrogen atoms. There is not much of it, C14 occurs in trace amounts, only making up as much as 1 part per trillion (0.0000000001%) of the carbon on the Earth. This amount of C14 is in balance, the amount created in the upper atmosphere balances the amount lost by the natural radioactive decay of the isotope.

All living things on earth, are made of chemicals that include carbon and, while living, the amount of C14 in them is in balance with the amount of C14 in the atmosphere. However when a living thing dies it no longer mixes the carbon in its body with that of the atmosphere and thus the amount of C14 it contains begins to reduce to levels below that found in the atmosphere because the C14 decays radioactively.

Thus items to be dated using C14 must contain carbon (wood, charcoal, hair and bones are good) and must have remained undisturbed since the organisms death. Also C14 decays rather quickly and is therefore only good for dating items that are less than about 60,000 years old.
