Radiocarbon dating problem

If this water is in contact with significant quantities of limestone, it will contain many carbon atoms from dissolved limestone.

This problem, known as the "," is not of very great practical importance for radiocarbon dating since most of the artifacts which are useful for radiocarbon dating purposes and are of interest to archaeology derive from terrestrial organisms which ultimately obtain their carbon atoms from air, not the water. Samples of coal have been found with radiocarbon ages of only 20,000 radiocarbon years or less, thus proving the recent origin of fossil fuels, probably in the Flood.Levels do happen to spike on a local and seasonal basis with changes in the carbon cycle, but carbon-14 is presumed to diffuse fast enough to ignore these tiny bumps.At least, that was the assumption until now."We know from atmospheric measurements over the last 50 years that radiocarbon levels vary through the year, and we also know that plants typically grow at different times in different parts of the Northern Hemisphere," says archaeologist Sturt Manning from Cornell University."So we wondered whether the radiocarbon levels relevant to dating organic material might also vary for different areas and whether this might affect archaeological dating."The tree rings were samples of Jordanian juniper that grew in the southern region of the Middle East between 16 CE.A comparison of radiocarbon ages across the Northern Hemisphere suggests we might have been a little too hasty in assuming how the isotope - also known as radiocarbon - diffuses, potentially shaking up controversial conversations on the timing of events in history.By measuring the amount of carbon-14 in the annual growth rings of trees grown in southern Jordan, researchers have found some dating calculations on events in the Middle East – or, more accurately, the Levant – could be out by nearly 20 years.This carbon – which has an atomic mass of 14 – has a chance of losing that neutron to turn into a garden variety carbon isotope over a predictable amount of time.

By comparing the two categories of carbon in organic remains, archaeologists can judge how recently the organism that left them last absorbed carbon-14 out of its environment.

Other radiometric dating methods such as potassium-argon or rubidium-strontium are used for such purposes by those who believe that the earth is billions of years old.

Radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded).

In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.

Radiocarbon is not used to date the age of rocks or to determine the age of the earth.

Over millennia the level of carbon-14 in the atmosphere changes, meaning measurements need to be calibrated against a chart that takes the atmospheric concentration into account, such as INTCAL13.
