Absorption Coefficient of Aluminium

[Lizze]

Hi. I am new here! I'm doing a experiment on the absorption of beta radiation of aluminium and I need help! Does anyone know what the absorption coefficient of aluminium? Or at least where I can find it. Thanks in advance!

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

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.

is it still there?
