Half-Life Simulation Practical

Extracts from this document...

Introduction

Half-Life Simulation Practical Aim: The aim of this practical is to use dice to model the process of radioactivity decay and to discover any relationships that might exist. I also want to find out the half-life of an element.

Middle

Later on, the number of dice is taken out in a smaller number and it eventually gets to zero. This is because when we do the experiment with dice, it is impossible to get to infinite because we can't break the dice into halves. The half-life of a substance is the time taken for half the atoms to decay. In terms of real decay, the half-life for atoms will go on forever because it never gets to zero. I have also found out the half-life of the source which is about 3.5 shakes (from looking at my graph. ...read more.

Conclusion

The reason for this is because in terms of real decay, it is random just like how the dice works. The only thing that's different is that in real decay, the half-life goes on forever, but with the use of dice, eventually the last die will be "picked out". I should also shake the box more to mix up the dice to make it fair so that I won't have the same numbers showing again. The errors of this experiment could be that the dice are not all the same because some dice may have slight problems on it which won't make the roll fair. Next time I can use new dice to do this experiment. ...read more.
