As filtration increases, the number of low-energy x-rays in the beam will decrease. Filtration is a technique used in radiography to remove low-energy x-rays from the X-ray beam, which do not contribute to the image but can increase the radiation dose to the patient. These low-energy x-rays are often attenuated by the filters placed in the path of the beam, typically made from materials like aluminum.

By removing these low-energy x-rays, filtration improves the overall quality of the x-ray beam, allowing only the higher-energy photons, which are more likely to penetrate tissues and contribute valuable diagnostic information, to reach the detector or image receptor. This process effectively enhances image quality while minimizing patient exposure to unnecessary radiation. Thus, with increased filtration, the intensity of low-energy x-rays in the beam significantly decreases.
