What: "Gamma rays are like a wind blowing over our lawn. It occasionally blows down a blade of grass but mostly it just passes through undisturbed."...and "Alpha radiation is like a big heavy ball rolled across a lawn. It doesn't go very far because it loses a lot of energy flattening out the bumps in the ground. In other words the heavy ball interacts strongly with the ground."
