| The photoelectric effect is an interaction between an x-ray and a(n) _________ electron that results in total x-ray absorption | inner-shell |
| Compton interactions, photoelectric absorption, and transmitted x-rays all contribute to _________________. | differential absorption |
| Coherent scattering is an interaction between _______ x-rays and atoms. | low-energy |
| If 5% of an incident beam is transmitted through a body part, then 95% of that beam was ______________. | attenuated |
| X-rays transmitted without interaction contribute to | the radiographic image |
