    Study Notes

    Attenuation of X-ray Beams

    • Attenuation reduces the intensity of an x-ray beam as it passes through matter.
    • Reduction results from absorption or deflection (scattering) of the x-ray photons.
    • Factors influencing attenuation include the beam's energy and the atomic number of the material absorbing the beam.
