WebIn fact, shielding may do harm by covering a part of the body the radiologist needs to see. If this happens, the doctor may need to repeat the imaging exam. As a result, the American Association of Physicists in Medicine (AAPM) recommends doctors stop using gonadal and fetal shielding during X-ray based diagnostic imaging. WebThe principles discussed also apply to monoenergetic x rays; in many cases of concern in x-ray shielding, however, the photons are produced in the bremsstrahlung process that yields a wide and continuous distribution of photon energies. Specialized shielding approaches have been developed to carry out shielding estimations for such x rays (e.g.,
