Carbon 14 dating seal austindating org
Carbon-14 is one form of radiometric test, but one very important feature distinguishes it from the others.
Other radiometric tests can be used only in determining the ages of volcanic rocks.
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 1940'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.
The Earth is constantly being bombarded by cosmic rays from outer space.
These rays strike nitrogen-14, found in high levels in the atmosphere, and transform this into carbon-14, a radioactive substance.
MYTH #2 Radiocarbon dating has established the date of some organic materials (e.g., some peat deposits) to be well in excess of 50,000 years, thus rendering a recent creation (6 to 10 thousand years ago) impossible.
Thus the age of a once-living thing can be calculated by measuring the amount of carbon-14 left in its tissues. In other words, the amount of carbon-14 in the dead tissue declines by half once every 5.570 years.
If these natural waters—which contain carbon-14—come into contact with the specimen, then some of the carbon-14 atoms they contain will pass into the specimen.
In that event, the specimen will test younger than it really is.
In that event, the specimen will appear to be older than it actually is.
Indeed, various concrete findings have revealed that carbon-14 dating is not all that reliable.
Carbon-14 dating, however, can be used to determine the ages of once-living things.
