Dear No name entered, Don't apologize. You're completely clear to me. You want to know which factor, of all the various factors, primarily affects how an element absorbs X-rays. Well, that factor is atomic number (Z) - and with it the element density. The x-ray mass absorption coefficient of elements tends to increase with increase in Z. I hope you like unambiguous answers? It turns out the mass absorption factor(cm^2/gm) is greater (in some cases ten greater) for lower energy x-ray photons.
