| Fluoroscopy-guided surgery | Scatter radiation from the patient during prolonged or repeated X-ray imaging. | Routine for staff in the room | Wear a correctly fitted apron, thyroid collar, and other required protective equipment. Maximize distance from the patient and stand on the detector side when practical. | The apron reduces exposure from scatter but does not replace time, distance, shielding, dose monitoring, or equipment optimization. |
| Interventional radiology | Potentially high cumulative scatter exposure during lengthy, high-dose procedures. | Routine for staff in the room | Use wraparound or equivalent protection when movement around the table is required, together with ceiling-suspended shields, table-side curtains, and personal dosimeters. | Lead-equivalent protection is less effective if it is damaged, poorly fitted, or positioned outside the radiation field. |
| Cardiac catheterization and electrophysiology | Repeated fluoroscopy and cine imaging can produce substantial occupational scatter. | Routine for staff in the room | Use an apron and thyroid protection; combine them with ceiling-suspended shields, table skirts, appropriate beam angulation, and dose tracking. | Protective garments should not be folded because creases can damage the shielding material. |
| Mobile C-arm procedures | Scatter from the patient, particularly when personnel remain close to the operating table. | Routine when personnel stay nearby | Wear protective clothing and keep nonessential personnel away. Position staff on the image-receptor side whenever feasible and follow the facility’s mobile C-arm protocol. | The exact dose depends on beam direction, distance, exposure settings, and the time spent near the patient. |
| Routine diagnostic radiography | Short exposures with staff generally able to leave the room or use a fixed barrier. | Usually not needed for staff | Staff should normally stand behind a structural barrier or leave the room. If remaining in the room is necessary, maximize distance and avoid the primary beam. | A lead apron is not a substitute for a controlled area, a protective barrier, or safe positioning. |
| Computed tomography | Scatter from the patient and gantry during image acquisition. | Used only when remaining in the room is necessary | Staff should normally operate from the control room. During exceptional patient-support situations, use appropriate shielding and stand as far from the gantry as practical. | Routine apron use for patients during CT can interfere with automatic exposure control and image quality; follow local radiology policy. |
| Portable radiography at the bedside | Scatter radiation in areas where fixed barriers may not be available. | Used when personnel cannot leave | Nonessential personnel should leave or move as far away as practical. Personnel who must remain should use a protective apron and avoid standing in the primary beam. | Other patients and visitors should be moved away or shielded according to the facility’s radiation-safety procedure. |
| Mammography | Low-scatter diagnostic imaging performed with personnel normally outside the room. | Not routinely required for staff | Staff should use the control-room barrier or leave the room during exposure. Patient shielding decisions should follow current clinical guidance and the examination protocol. | Aprons provide little benefit when the person is already protected by distance or a structural barrier. |
| Dental and panoramic X-ray imaging | Low occupational exposure when the operator uses distance and remains out of the beam. | Not routinely required for operators | Use the recommended operator position or a protective barrier. A patient apron may be considered according to local regulations and current professional guidance. | Never hold the X-ray tube or image receptor during an exposure. |
| Pregnant or potentially pregnant staff | Occupational exposure to scattered X-rays, with additional attention to fetal dose. | Based on duties and exposure assessment | Use the same core controls—time, distance, shielding, and monitoring. Notify the radiation-safety or occupational-health service so duties and monitoring can be reviewed. | Pregnancy declaration does not automatically require removal from radiation work; a lead apron alone does not guarantee fetal protection. |
