[Reduction of doses in teleradiography of the spine. Criteria of radiation protection and studies of dosimetry].

To reduce the radiation exposure during full spine X-ray examinations, the following techniques were instituted: 72" tube to film distance; X-ray beam collimation; fast screen-film combination (rare earth gradual screens with high speed films); additional compensation filters; shielding of the most radiation-sensitive organs. Dosimetric measurements are reported. A very high reduction in exposure, above all of breasts and gonads, was obtained, without significant loss in the quality of radiographs.
