Homework Help: Mass attenuation coeffcient relation to kinetic energy

  1. Nov 26, 2008 #1
    the mass attenuation coefficient is related to the maximum kinetic energy of the beta ray spectrum ( T max) by this equation

    mu subscribe m (symbol) = 1.7 / (1.14
    T max)
    the problem here is that the denominator in my text is in the form of a matrix and as well all know a matrix doesn't give you a number so how do i evaluate it.

    Hi shonen! Welcome to PF! :smile:

    Can you type out the exact equation from your text?

    Here's a ยต to help you, and if you don't know how to tex a matrix, use the Code tag :wink::
