a: beta radiation ~
b: snipers bullet
What:
"There are 3 sorts of radiation, alpha, beta and gamma. Imagine if you will that you are trying to shoot a target on one side of London from the other. Gamma radiation is like a fine laser beam, beta radiation is like a snipers bullet and alpha radiation is like firing a double decker bus out of a very large cannon. It won't get very far but is bound to damage something on the way."
