This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
You probably have seen or read news stories about fascinating ancient artifacts.
If a fossil contains 60% of its original carbon, how old is the fossil? That means this is how long it takes for half the nuclei to decay.
After 5600 years, if we start with a gram, we end up with half a gram.
Howstuffworks "How Carbon-14 Dating Works" radiocarbon WEB-info The method How accurate are Carbon-14 and other radioactive dating methods?
Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.
Much of the information presented in this section is based upon the Stuiver and Polach (1977) paper "Discussion: Reporting of C14 data". 1890 wood was chosen as the radiocarbon standard because it was growing prior to the fossil fuel effects of the industrial revolution.
A copy of this paper may be found in the Radiocarbon Home Page The radiocarbon age of a sample is obtained by measurement of the residual radioactivity. T (National Institute of Standards and Technology; Gaithersburg, Maryland, USA) Oxalic Acid I (C). The activity of 1890 wood is corrected for radioactive decay to 1950.
Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
When granite rock hardens, it freezes radioactive elements in place.
