“…Some authors [1,5,8,9] concluded that the irradiation dose can be reduced by up to 50% without degrading the image quality of fields in the lung but not in the mediastinum, upper abdomen, or retrocardiac region. Most studies on the usefulness of radiographs taken in the ICU [4,5,8,[10][11][12][13][14][15][16][17] have described an elevated frequency of this examination [5,15], identifying an 'excess' of x-rays that do not contribute to the diagnosis of patients [4]. Methods proposed to reduce the radiation received by healthcare personnel, especially radiology technicians [8,[18][19][20][21], include: customisation of the x-ray system, workflow adaptations, and lead shielding devices, including tableside lead drapes, ceiling-mounted lead acrylic protection, backscatter shields, and lead gloves, among other measures.…”
