Reliability of radiometric dating
It furnishes some good evidences that creationists often use.
But we won't discuss the C-14 method in this article.
I can look in my scientific journals and see apparent discrepancies in dating techniques.
Some may be discrepancies…some may just need a bit further explanation.
If there are possible discrepancies, how can I accept these dates as reliable?
Radioactive Dating There are basically two different kinds of radioactive dating methods.
Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.
Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings.
The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry.
But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science.
Search for reliability of radiometric dating:
By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.
