Ever heard of Plutonium? It's the stuff we use in our nuclear things -- weapons, submarines, etc. Plutonium has a half-life of 24, years. In 24, years, you'd still have 50 pounds left In another 24, years, you'd still have 25 pounds left. This stuff just won't go away! This is why it is such a big concern when a nuclear submarine sinks Eventually, the salt water will eat through the steel and release the Plutonium which, as you know, is quite lethal.

They usually talk about either trying to raise the sub or encase it in concrete where it rests. The last figure I heard was that there are currently eight nuclear subs on our ocean floors. Now that I've completely depressed you Hey, did you know that YOU are radioactive? You've got this stuff in you called Carbon It comes from cosmic rays that rain down carbon dating half life problem the earth and us from outer space. By the way, you are mostly Carbon, which is not radioactive.

That's why we are called "Carbon-based life forms. Scientists use Carbon to make a guess at how old some things are -- things that used to be alive like people, animals, wood and natural cloths. It doesn't work for sea creatures and other things that are under water. Cosmic rays can't get through the water. Anyway, they make an estimate of how much Carbon would have been in the thing when it died Then they measure how much is left in the specimen when they find it.

This is where the half-life comes in You can use either of these formulas. I'm going to use the second one since it's easier and it's used carbon dating half life problem often. More Ways to Use This Stuff. Here's one of the formulas they use: If we mess with this a bit, we can make it simpler: Solving for Time and Rates.
