There are two reasons uncalibrated dates must be mentioned: 1) this prevents people from making up any number they please, and 2) it is for the sake of posterity, where future scientists can check the results and apply new ideas of calibration. Radiocarbon dates are affected by many outside factors.The accuracy of the machines is not in question (especially modern ones, which are astoundingly accurate when properly zeroed in). But, any source of old carbon in the ancient environment can affect the amount of C-14 in a sample.

Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

To understand this process we must first understand a little bit about the atoms themselves and how they get their names.

Most carbon atoms have six positively charged protons and six uncharged neutrons.

I understand calibration might have something to do with this, but then in the article it says in italicized words that the uncalibrated date “Must Always Be Mentioned”. CMI’s Dr Rob Carter responds: Anthony, As a fan of biblical archaeology, I was asked to address your question.

But when I read articles about the results, they never mention the uncalibrated data, which could actually be correct. I am not an expert in every subject that impinges on the discussion, but I will do my best.

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

Three of the Carbon isotopes (C) are found in nature.

The rest of the carbon isotopes are only of laboratory interest.

Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.
