Good luck with your new WWWBoard. It could be very good timing for me, if one of your participants can guide me to a relevant URL or forum that can address my question - better yet, perhaps provide an answer to my question.
I have an x-ray system that can detect a defect material, metal or alloy, of some minimum size in a metal host. How can I calculate the minimum detectable size of a different defect metal or alloy?
I have an equation that should yield tha answer, but it requires an absorption coefficient for the materials of interest. When I search databases for x-ray material absorption coefficients, I find tables of data which I do not know how to utilize. It is unfortunate for me that my equation wants a single value.
