This is called the half-life—the amount of time required for one-half of a given number of atoms to disintegrate. The plot of the number of tiles as a function of the number of turns looks like this: Again, I made radioactive spheres disappear when they decayed.This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.The carbon-14 isotope would vanish from Earth's atmosphere in less than a million years were it not for the constant influx of cosmic rays interacting with molecules of nitrogen (NFigure 1: Diagram of the formation of carbon-14 (forward), the decay of carbon-14 (reverse).
It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.
The rate of decay depends upon the number of atoms you have.
This means that as more of these atoms decay you have a lower rate of radioactive decay. If you roll a one, then that object decays and turns into something else.
When an element undergoes radioactive decay, it creates radiation and turns into some other element.
Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance to decay.
