Absorption Coefficient of Aluminium

  1. Dec 12, 2006 #1
    Hi. Im new here! I'm doing a experiment on the absorption of beta radiation of aluminium and I need help!! :redface: Does anyone know what the absorption coefficient of aluminium? Or at least where I can find it. Thanks in advance!! o:)

    P.S. Sorry if I've posted in the wrong part of the forum :redface:

    I can't tell you where to find this info, but I can tell you that the absorption coefficient is a function of the energy of the electrons. So, you'd have to specify the mean energy (or energy range) to have a meaningful number.

    Google found some data:

    The "particle data group" used to have a small pdf about properties of the materials, with this kind of information.
