[Gate-users] How to get the linear attenuation coefficients ?

[sebnem erturk]

Hi Joe,

You can use XCOM program  to learn linear attenuation coefficients. (you can
download this program from  below link)
unit of linear attenueation coefficent is cm^-1.

μl is called the linear attenuation coefficient of the absorber. It has
dimensions (thickness)-1 and usually is expressed in cm-1

hope it helps,
