Radiocarbon dating is accurate for dates ranging

Modern radiocarbon dating uses tree-ring chronologies to produce the calibration curve.Because the radiocarbon to stable carbon ratio in the atmosphere has fluctuated over time, there are "wiggles" in the calibration curve.An “isotope” is any of several different forms of an element, each having different numbers of neutrons.

For example, modern biblical chronology dates Noah's Flood to 3520 /- 21 B.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

A common misconception about radiocarbon dating is that it gives a precise date---3577 B. In actual practice radiocarbon dating can only give a range of dates for a given sample---3650 to 3410 B.

C., for example---the true date lying somewhere in that range.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Recall that atoms are the basic building blocks of matter.Thus it is possible in some instances for two samples from a few decades apart to have the same radiocarbon concentration today, and hence the same apparent radiocarbon age.This happens whenever there is a wiggle in the curve at the time the samples died.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.The technology involved is fascinating and impressive.The number of neutrons in the nucleus can vary in any given type of atom.So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.

As a rule, carbon dates are younger than calendar dates a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roughly equates to 24,000.…

    The great promise of radiocarbon C14 dating is that it provides a method for dating and sequencing specific prehistoric events. On the Aucilla. Wood is a very reliable material for C14 testing. By inserting a C14 date of 10,000 ± 100 for our branch, OxCal produced a range of calibrated dates with different confidences.…

    They found large variations in the radiocarbon 'dates' of objects of known age sent to 38 radiocarbon 'dating' laboratories around the world. Thirty-one of the labs gave results that the British group called unsatisfactory. Their results were 'two to three times less accurate than implied by the range of error they stated.…

    Sep 20, 2007. Carbon-14 14C, also referred to as radiocarbon, is claimed to be a reliable dating method for determining the age of fossils up to 50,000 to 60,000 years. If this claim is true, the biblical account of a young earth about 6,000 years is in question, since 14C dates of tens of thousands of years are common.1.…
