Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.
Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
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.
However, creation scientists have carbon-dated fossils, diamonds, and coal that are all supposed to be millions of years old.
Nevertheless, they all have detectable amounts of carbon-14 in them.
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.
One of the more recent developments is the carbon dating of bones and other carbon-containing materials that are supposedly millions of years old.
Carbon dating uses the radioactive decay of carbon-14 into nitrogen-14, which currently has a half-life of 5,730 years.
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.
