Mass attenuation coeffcient relation to kinetic energy

[shonen]

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!

Can you type out the exact equation from your text?

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