All living organisms absorb C-14, an unstable form of the element carbon that slowly decays into nitrogen-14 (N-14). During its lifetime, an organism continually replenishes its supply of C-14 by breathing and eating. After the organism dies and becomes a fossil, C-14 decays without being replaced. Scientists know the rate at which C-14 decays and can detect the electrons that C-14 emits as it decays. Counting these electrons dates the fossil because older fossils contain less C-14 and emit fewer electrons. Appears in these articles: Carbon; Neutron; Dating Methods Archaeology ... Feedback

Carbon-14 Dating Shows that the Earth is Young
by Curt Sewell Summary This article describes Carbon-14, and how it's distributed throughout all living objects. We also discuss the basics of its radioactive behavior, and the principles of the Carbon-14 Dating Method, including its assumptions. In the last part of this article, we discuss some new scientific evidence, showing that some basic assumptions are in error. At least one of these errors actually becomes a strong evidence that the Earth cannot be more than about 100,000 years old. Setting the Stage I'd like to begin this article by describing one example of Carbon-14 dating, performed by one of the leading labs in the dating field. Their carefully done report is a classic illustration of the controversy that exists between most secular scientists and most Biblical creationary scientists. The Hawkesbury Sandstone formation, near Sydney, Australia, is a massive and spectacular mass of hard rock, often used for construction of buildings in Sydney.(1) There are three principle layers of rock massive sandstone, sheet sandstone, and some thin mudstone. Although it is massive (7,700 square miles in area and up to 820 feet thick) it shows many of the features of deposition in fast-flowing waters. There are cross-beds, sloping at about 20 o , some are up to 20 feet high, within the flat-lying strata. These were probably formed by huge sand-waves, swept by massive water flows. A number of lenses of mudstone contain many fossils, mostly of fish, sharks, and aquatic plants. Geologists have assigned it to the Middle Triassic 'age' (225 - 230 million years old), based on fossil content and the relative sequence of rock layers in the Sydney Basin. This "stratigraphic dating" is the technique most widely used by conventional geologists who believe in the long timescale of the Geologic Column.

...to be included in an upcoming book, Persuaded by the Evidence , by Curt Sewell When I was in school in the 1930's and early 40's, I had never heard of anyone with an interest in science who actually believed early Genesis. I was raised in church, and believed the Bible (except for early Genesis), since my church was liberal and I hadn't become a born-again Christian. I had an active interest in science, and so I believed in evolution and ancient Earth-age, because that was what they taught in school. That belief was reinforced when the Army put me in the Manhattan Project (developing the first atomic bomb) and I met a number of scientists whose names you've all heard of. Later, while I was Chief Engineer of Isotopes Inc., several of our top staff were Ph.D.'s, including one who was also Professor of Geochemistry at Columbia University. He and a few others were Wheaton graduates, and Christians, who believed in Progressive Creation. We often had lunch together, and the subject of origins was one of our favorite "arguing points." By that time I had become a born again Christian, and studied the Bible.

How Creationists Misrepresent the Carbon-14 Dating Method By Dr. Robert Holloway
In the continuing disagreement between religious fundamentalists and mainstream science, the subject of various dating methods is often discussed. Typically, fundamentalists are upset by the implications of the scientific dating methods since these methods often show an earth must older than the fundamentalists are willing to accept. Even the radiocarbon method often comes in for criticism although it is suitable only for objects less than 50,000 years old. This criticism usually comes from Young Earth Creationists who believe that the earth is less than 10,000 years old. Because the radiocarbon method can reliably date carbon containing objects much older than this, they apparently feel uncomfortable with the results. One such critique regarding the carbon-14 method was published by Apologetics Press of Montgomery, Alabama. It is available on the Internet at the following link: Apologetics Press article on Carbon-14 The article is by Trevor Major, who apparently has some education in science. He presents the basic theory behind the C-14 method in a clear and understandable manner. However, his experience with dating methods is apparently limited to a superficial review that focused mainly on writing by other creationists. I say this because he fails to understand a crucial point about the dating method and also because 6 of his 11 references are from creationist authors. Major mentions five points that he considers weaknesses of the radiocarbon method. The one he considers most critical is what he claims to be the assumption that the rates of C-14 production and decay are in a state of balance and have been in balance during the age range for which the method is suitable. In regard to this alleged assumption, Major makes the following statement:

Chronolgy - Calibration - Relevance - Etcetera Addendum : Radiocarbon or Carbon-14 dating is probably one of the most widely used and best known absolute dating methods. It was developed by J. R. Arnold and W. F. Libby in 1949 and has become an indispensable part of the archaeologist's tool kit since. It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences. This allowed for the establishment of world-wide chronologies .....

Radiocarbon Volume 43 : Number 3 : Page 1191 1202 With the further development of calibration curves all dates from the Proto-Neolithic and Neolithic cultures can now be calibrated. A total of 1300 C-14 dates were evaluated - leading to the selection of 731 reliable dates. The C-14 dates are derived from 160 sites across the Middle East. The period with Proto-Neolithic Cultures began around 12500 calibrated BC and lasted for more than 4000 years until circa 8400 calibrated BC. The advent of the true Neolithic in the Near East - with agriculture and livestock breeding - can reasonably be dated a little before 8000 calibrated BC; or more correctly between 8300 and 8000 calibrated BC during a phase that is called Middle Pre-Pottery Neolithic B (PPNB) in the Levant .....

"Due to the non-monotonic decay of the C-14 level with time over this period (since about 1650) it is impossible to date any material accurately using C-14."
What do you estimate is the uncertainty level? That is, how inaccurate is the method over that period? Also, how accurate is it in the range of years in which it is "accurate"?
Thanks, Steve Price

Slide 13 of 13 Notes:
    The figure shows how Carbon-14 decays. By matching patterns of ring growth in wood samples, and correlating those with carbon-14 activity, the proportion of carbon-14 to carbon-12 in living material can be traced back tens of thousands of years, producing a very accurate way to measure the age of old organic materials that were living material when the tree rings were formed.

Bottom of Lake Refines Carbon Dating Technique
By Kenneth Chang
ABCNEWS.com
Feb. 23 - Each spring, tiny plants bloom in Lake Suigetsu, a small body of water in Japan. When these one?cell algae die, they drift down, shrouding the lake floor with a thin, white layer.
The rest of the year, dark clay sediments settle on the bottom. The alternating layers of dark and light count the years like tree rings. That has allowed scientists to fine?tune a technique called carbon-14 dating, which is used to pin down dates for artifacts tens of thousands of years old.
