By Griffon , December 29, in Physics. I've been poking about on the internet again as you do and found a whole load of stuff by creationists about the problems with carbon 14 radiometric dating. Specifically they report with some glee that coal has been found to contain measurable amounts of carbon14 which it should not of course because it is about million years old and dates from the carboniferous period. C14 has a half life of years and is only good to date objects to 50, years or so. Although I can find any number of references to this seemingly vital finding on the creationist sites, I can find almost no attempt to refute or explain this anomaly on serious science sites. This looks like a serious oversight to me.
Carbon dating accuracy called into question after major flaw discovery
Carbon Dating A fossil contains 2. It is estimated that the fossil originally contained grams of carbon By calculating the amount 5, years, 10, years, …, 35, years ago, estimate the age of the sample to the nearest 5, years. Refer to the formula for C t at the end of Example 7. Median response time is 34 minutes and may be longer for new subjects.
Lesson Carbon dating problems
The carbon clock is getting reset. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct. Carbon dating is used to work out the age of organic material — in effect, any living thing. The technique hinges on carbon, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate. Organisms capture a certain amount of carbon from the atmosphere when they are alive.
