The calibrated age (cal years bp) is the calendar year equivalent of the conventional radiocarbon age because of the constant improvements to calibration data, there is no guarantee that one person's cal bp will be the same as another's some authors use 2000 ad as a base, some use 1950 ad. Carbon dating is unreliable for objects older than about 30,000 years, but uranium-thorium dating may be possible for objects up to half a million years.

Radiocarbon dating compares the amount of radioactive carbon 14 in organic plants and animals to reliably estimate when the object died radiocarbon dating compares the. Limitations of and extensions to the c limitations of, & extensions to, the dating millennia or 100 millennia bp the ratio of c-14 to carbon-12 in living. Creation science organizations have found carbon dating results which give anomalous results for example, different samples from the same frozen musk ox in alaska gave age estimates of 24 and 17 thousand years bp.

In this educational animated movie about science learn about fossils, isotopes, nitrogen, and paleontology.

In the movies, scientists use “carbon dating” to determine the age of ancient artifacts and dinosaur bones but what is the real science behind carbon dating. Carbon-14 dating: carbon-14 dating, , method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14) carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the earth’s atmosphere the neutrons required for this reaction are produced by cosmic.

It should be noted that a bp notation is also used in other dating techniques but is defined differently, as in the case of thermoluminescence dating wherein bp is defined as ad 1980 it is also worth noting that the half-life used in carbon dating calculations is 5568 years, the value worked out by chemist willard libby, and not the more accurate. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14 c), a radioactive isotope of carbon.

In radiocarbon dating, whatever is being dated is incinerated until all that remains is carbon or carbon dioxide gas it is therefore prudent to save some of the sample for further testing, should that become necessary.

The initials bp (or bp and rarely bp), when placed after a number (as in 2500 bp), means years before the present archaeologists and geologists generally use this abbreviation to refer to dates that were obtained through the radiocarbon dating technology while bp is also used generally as an.
