Carbon 14 dating information
When it comes to dating archaeological samples, several timescale problems arise.
For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).
So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method.
The activity of the sample is measured to be 0.770 times the Carbon-14 activity of living plants. (The half-life of the Carbon-14 isotope is 5730 years.) F = A * (1/2)^(t/k), where F is the current Carbon-14 activity, A is the carbon-14 activity of a living plant, k is the half-life, and t is the number of years which has passed.
