Carbon dating affected by water

The field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by Libby in the late 's. It is, therefore, not surprising that many misconceptions about what radiocarbon can or cannot do and what it has or has not shown are prevalent among creationists and evolutionists - lay people as well as scientists not directly involved in this field. 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. MYTH 1. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.

THE hard-water effect is a recognized source of error in radiocarbon dating. It causes ages to be over-assessed and arises when the material to be dated, such as mollusc shell or plant, synthesizes its skeleton under water and so uses bicarbonate derived in part from old, inert sources.

It is usually stated that the maximum possible error is equivalent to the half-life of 14 C, 5, yr Libby scale , but it rarely amounts to as much as this. Moreover, in an isolated dating it is not only impossible to evaluate, but even to know whether there is any over-estimation, but if the sample consists of tree wood, or the leaves, twigs or seeds of wholly terrestrial plants, then it can be assumed that no hard-water error is present.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years.

Radiocarbon dating

The basis of radiocarbon dating includes the assumption that there is a constant level of carbon 14 in the atmosphere and therefore in all living organisms through equilibrium. Carbon 14 is a naturally occurring isotope of the element carbon and is called radiocarbon. It is unstable and weakly radioactive. Another characteristic of carbon 14 is that it is continually being formed in the upper atmosphere as a product of the reaction between neutrons produced by cosmic rays and nitrogen atoms. These carbon 14 atoms then instantaneously react with oxygen present in the atmosphere to form carbon dioxide.
