What is the definition of the coefficient of linear and mass

  1. Jan 12, 2016 #1
    hi,
    i'm student in a university. I do not understand the definition of these concepts, and I would like to know the properties of these and it depends
    questions like
    They depend on the material used?
    the atomic number?

    thanks for answering
    capisko,

    Coefficients where, for what?

    yes, i'm sorry.
    I refer to attenuation coefficients of radiation

    Which radiation? ...

    Independent of the type of radiation: yes, it depends on the material used. On the atomic number but also on the density of the material.

    ok thanks! and, which is the difference in coefficient of linear and mass attenuation?

    Linear in what?
    Coefficients in which formula?
    There is a lot of context missing here. I cannot even tell if it is nuclear or particle physics (gamma rays interacting with nuclei or free electrons) or atomic/solid state physics (e.g. visible light in matter).

    I assume that you've tried web searches on these concepts. I suggest that you give us links to definitions that you've seen already, and try to tell us what you don't understand about them. Then we will have something specific that we can try to clarify. Someone here could try to write up an explanation from scratch, but how would it be more likely that you would understand it than the other web pages out there which we haven't even seen?

    Also, as mfb said, context is important.
