The amount of filtration of the x-ray beam is specified by and based on the voltage potential (keV) used to produce the beam. The thickness of filter materials is dependent on atomic numbers, kilovoltage settings, and the desired filtration factor.
X-rays are a form of electromagnetic energy just light-rays and micro-waves are. X-rays have more energy than light-rays so they can penetrate and travel through materials that light-rays cannot. Film is sensitive to x-rays in the same way that it is to light-rays, so X-rays can be used produce images. X-rays that are sent through an object can produce an image on a piece of film placed on the opposite side of the object.
