Radiocarbon Dating: A Closer Look At Its Main Flaws | Great Discoveries in Archaeology
Radiocarbon dating has been used to determine of the ages of . to distinguish if the radiocarbon is affected and therefore wrong or if it's not.". By measuring the amount of carbon in the annual growth rings of trees grown in southern Jordan, researchers have found some dating. In some cases, the latter ratio appears to be a much more accurate gauge of age than the customary method of carbon dating, the scientists.
His technique, known as carbon dating, revolutionized the field of archaeology.

An isotope is a form of an element with a certain number of neutrons, which are the subatomic particles found in the nucleus of an atom that have no charge. While the number of protons and electrons in an atom determine what element it is, the number of neutrons can vary widely between different atoms of the same element.
Nearly 99 percent of all carbon on Earth is Carbon, meaning each atom has 12 neutrons in its nucleus. The shirt you're wearing, the carbon dioxide you inhale and the animals and plants you eat are all formed mostly of Carbon Carbon is a stable isotope, meaning its amount in any material remains the same year-after-year, century-after-century. Libby's groundbreaking radiocarbon dating technique instead looked at a much more rare isotope of carbon: Unlike Carbon, this isotope of carbon is unstable, and its atoms decay into an isotope of nitrogen over a period of thousands of years.
New Carbon is produced at a steady rate in Earth's upper atmosphere, however, as the Sun's rays strike nitrogen atoms. Radiocarbon dating exploits this contrast between a stable and unstable carbon isotope.
During its lifetime, a plant is constantly taking in carbon from the atmosphere through photosynthesis. Animals, in turn, consume this carbon when they eat plants, and the carbon spreads through the food cycle. This carbon comprises a steady ratio of Carbon and Carbon When these plants and animals die, they cease taking in carbon.

Dates up to this point in history are well documented for C14 calibration. For object over 4, years old the method becomes very unreliable for the following reason: Objects older then 4, years run into a problem in that there are few if any known artifacts to be used as the standard.
Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
He understood that archaeological artifacts were readily available. After all, this what the archeologist guessed in their published books. Some believe trees are known to be as old as 9, years. They use tree rings as the calibration standard.
A lot of people doubt this claim for various good reasons I wont go into here. We believe all the dates over 5, years are really compressible into the next 2, years back to creation.

So when you hear of a date of 30, years for a carbon date we believe it to be early after creation and only about 7, years old. If something carbon dates at 7, years we believe 5, is probably closer to reality just before the flood.
Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years. One of the impressive points Whitewall makes is the conspicuous absence of dates between 4, and 5, years ago illustrating a great catastrophe killing off plant and animal life world wide the flood of Noah!
I hope this helps your understanding of carbon dating. If you have any more questions about it don't hesitate to write. I just listened to a series of lectures on archaeology put out by John Hopkins Univ. The lecturer talked at length about how inaccurate C14 Dating is as 'corrected' by dendrochronology.
