Cambridge carbon dating

Misconception #2: Carbon dating can be used to date virtually anything Another misconception people have about carbon dating is that it can be used to date virtually anything.Carbon dating can only be used to date objects that were once living or even apart of a living organism. It cannot be used to directly date inorganic objects, such as rocks (other radioactive dating methods are used to date radioactive rocks).After about 8 half-lives, the remaining amount of C-14 (if there is any remaining) is too small to be measured.For this reason, it is simply impossible for carbon dating to give dates as old as millions of years. Closed systems, void of any contamination and without loss of the parent element (C-14) or daughter element. Known amounts of parent and daughter elements present from the beginning. If the decay rate of C-14 were not always constant, then this would be devastating to the technique's credibility.Instead, it can only give up to approximately 50,000 years. Unfortunately, dating methods such as the carbon dating method have only been around for a short period of time.Assumptions While this dating method sounds pretty good and simple enough to understand, there are some assumptions that aren’t often pointed out. So far, no known environmental factors have been able to significantly cause the decay rates to vary.

How radioactive carbon is formed Normal carbon atoms weigh 12 atomic mass units, while a radioactive form of carbon weighs 14 atomic mass units, which is called carbon-14 (C-14). It is estimated that only one out of every trillion carbon atoms is C-14.

With this said, it would be worth while to check out this feedback session which does seem to suggest that there might have been an accelerated decay rate in the past, at least for the uranium-lead method.

“It is important to realize that an accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation.

The displaced neutrons bond with nitrogen-14 (N-14) converting it into C-14.

Because C-14 is radioactive, it is unstable, and is constantly decaying back into N-14.

Ironically, despite its popularity, it is also one of the most misunderstood methods of dating.
