Er der en som er god til engelsk og lige vil se mit abstract igennem, er nemlig ikke så god til engelsk. 

This project investigates radioactive decays and coupled differential equations. Radioactive nucleus decay after certain of time. They can decays after different types of radioactive decays as alpha decay, beta decay and gamma decay. And all this is very exciting because a special law, named the Law of Radioactive Decay descripted how the number of radioactive nucleus decrease exponentially with the time. Though this I have make an experiment with a radioactive liquid, and the experiment it was observed that my radioactive liquid decreased exponentially with the time, the results were as the Law of Radioactive Decay has said. But you can also make another model where you solve this problem numerically, this method is called Eulers method. And it was exiting to see how close the two results are. With this method you can also make an analysis of a couple of decays.
