How do scientists use radiometric dating
This decay is an example of an exponential decay, shown in the figure below.
Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.
As long as an organism is alive, the amount of C-14 in its cellular structure remains constant.
But when the organism dies, the amount of C-14 begins to decrease.
A fear of God and reverence for His Word is the beginning of wisdom.
Starting with the Bible and developing a model for dating events in earth history will lead us to the truth.
Scientists know the half-life of C-14 (5,730 years), so they can figure out how long ago the organism died.
It takes a certain amount of time for half the atoms in a sample to decay.This has to do with figuring out the age of ancient things.If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.A useful application of half-lives is radioactive dating.
