Lead-lined X-ray doors

It is set for each room by a qualified radiation protection adviser or medical physicist, using shielding calculations based on the equipment, its workload and the occupancy of neighbouring spaces. The door normally needs the same lead equivalence as the wall it sits in. Send us the shielding report or the mm Pb figure for each door and we will build to it.

Radiation travels in straight lines and will pass through any gap in the shielding. If the leaf is lined but the frame is not, the joint between leaf, frame and wall becomes a path for scattered radiation. The lead in the leaf should overlap the lined frame, and the frame lining should overlap the wall shielding, so there is no direct line through the opening.

Yes. Vision panels use lead glass, which is rated by its lead equivalence in mm Pb. The glass and the lead in the glazing frame should give the same protection as the rest of the door. Panels are useful at control rooms and treatment rooms where staff need to watch the patient during an exposure.

Lead-lined doors are heavy, so the choice often comes down to space and use. Sliding doors save floor space and handle large leaves well on heavy-duty track, which suits busy CT and catheterisation rooms with bed traffic. Swing doors suit smaller rooms and lower traffic but need hinges sized for the weight. In both cases the overlap at the edges must keep the shielding continuous.

Lead lining and fire rating can be combined where the room wall is also a fire compartment wall, but the combination must fall within a tested fire door design. Tell us both the lead equivalence and the fire rating required at enquiry stage. Lead time depends on these, the sizes and the hardware. Within Jordan, doors are typically delivered within 1 to 2 weeks; for export, lead time depends on quantity.
