thank Q.means that , if the liquid is polymer, so I need to use the percentage of monomer? and water ?
actually, I need to find Absorbed dose in my gel from X-ray machine..using electrometer, we got charge,then sbstitute into that formula..am I right Dr?
Dose phantom = Dose air x ( mSwall / mSair ) x ( mass absorption coefficient phantom/ mass absorption coefficient of wall material ).
if I want to to find absorbed dose in a type of liquid ( combined different type ), how to find the absorption coef?
