1. The problem statement, all variables and given/known data Does alpha and beta rays obey the “Exponential law of attenuation”? Explain. 3. The attempt at a solution I'm ashamed to be even asking this, but hey I am anyway. I was thinking that they do follow the exponential law of attenuation. However, I can't say that I'd be able to explain it properly... Is this right? I mean I know that the range of alpha particles and beta radiation is much less than that of gamma and x-rays which makes it much easier to attenuate, but I can't really explain why I think that they would follow and exponential law of attenuation.
