If I'm being asked to calculate the attenuation of a certain type of radiation, what does that actually mean? Is ##\frac{I}{I_0}## the attenuation of the radiation? I'm just confused between things like attenuation and the attenuation coefficient and attenuation length, I think. So what is the quantity attenuation and how is it calculated? There'll be different equations in different scenarios probably, I'm not after a specific equation just something like 'it's the fraction of absorbed radiation...' .
Thanks for any help, that's quite a rambling question! :)
