Carbon dating myths and facts

As you may know, carbon 14 is produced in the upper atmosphere when cosmic radiation interacts with nitrogen gas, converting nitrogen 14 to carbon The second characteristic of the measurement of radiocarbon is that it is easy to contaminate a sample which contains very little radiocarbon with enough radiocarbon from the research environment to give it an apparent radiocarbon age which is much less than its actual radiocarbon age. Comedian Lewis Black, who by no stretch of the imagination is a knowledgeable evolutionist, argues.

Radioactive Carbon

You need to understand how carbon 14 dating works to understand why correction factors are necessary. Promoting carbon dating myths and facts into life times since success things forgetting their sorry history, swallowing down these whoppers!. He received his Ph. If this water is in contact with significant quantities of limestone, it will contain many carbon atoms from dissolved limestone.

Since limestone contains very little, if any, radiocarbon, clam shells will contain less radiocarbon than would have been the case if they had gotten their carbon atoms from the air.

These carbon 14 atoms combine with oxygen to form carbon dioxide gas, which is absorbed by plants. The shells of live freshwater clams can, and often do, give anomalous radiocarbon results.

by Gerald A. Aardsma, Ph.D.

There is no question they are right about that. Reports of young radiocarbon ages for coal probably all stem from a misunderstanding of one or both of these two factors. The global warming folks are quick to point out that there are measurable changes in the amount of carbon dioxide in the atmosphere. Since aboutthermonuclear tests have added considerably to the C14 atmospheric reservoir.

Calibration of Carbon 14 Dates

The point is that there is so little carbon dioxide in the water and atmosphere, that comparatively small changes in amounts of carbon cause large percentage changes.

It's like trying to figure out how long a candle has been burning, without knowing the rate at which it burns, or its original size. The myth is that radiocarbon dating can accurately establish exact dates of the death of organic remains almost as far back as 50, years.

But, if the Earth is less than 6, years old, as some creationists claim, then it might be possible to find carbon 14 in coal or dinosaur bones. We will leave it to others to argue whether or not changing the amount of carbon dioxide in the atmosphere from 0.
