Diamonds and carbon dating
-14-dating The issue is: How does one detect C14 in objects? There is some background radiation from other sources, which fluctuates a bit.
Given the nature of the material being covered, this will be a , something that creationists prefer to avoid at all costs, I shall first begin with a discourse on the underlying physics of radionuclide decay, the precise mathematical law that this process obeys, and how that law is derived, first derived empirically, courtesy of a large body of work by scientists such as Henri Becquerel, Marie Curie, Ernest Rutherford and others.
Once the data has been collected, transformed and plotted, the end result should be a nice curve.
At this point, we're interested in knowing what sort of curve we have, and there are two ways we can determine this.
-14-dating C14 is found in diamonds, oil, dinosaurs. Even if there was no C14 left, you´d get the occassional outlier in background radiation.
This means that at some point your radiation from C14 would be less than the fluctuations in background, making it untdetectable.
A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
How do scientists know how old an object or human remains are?
As well as the most familiar modes of decay, namely α and β decay, other decay modes exist, and a full treatment of the various decay modes possible, along with the underlying quantum physics, is beyond the scope of this exposition, as it requires a detailed understanding of the behaviour of the appropriate quantum operators, and as a corollary, a detailed understanding of the behaviour of Hilbert spaces, a level of knowledge that is, sadly, not widespread.
You probably have seen or read news stories about fascinating ancient artifacts.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
One way is to take the transformed data set, comprising count values c on the horizontal axis.
This should give a reasonable approximation to a straight line, and the slope of that straight line, obtained via regression analysis, will give the first approximation to the decay constant k.
Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
