# How can radiation be stopped by different materials?

 P: 2 1. The problem statement, all variables and given/known data Hi guys First post here. Im currently trying to complete a BTEC science assignment and have come across a question in which i just can not find the answers to. Ive been searching it up on the internet and cant find any information. Here it is: Research how each of the different types of radiation can be stopped by different materials. 2. Relevant equations 3. The attempt at a solution I have managed to find out the three different types of radiation which are: Alpha, Beta and Gamma. I have also found out that their penentration ability has a key role in how they can be stopped but apart from that i cant find anything. If anybody could help it would be a great help and greatly appreciated Many thanks in advance Sciencefreak.
