Lead-lined radiation shielding doors
High-quality door systems for hospital X-ray diagnostics, CT, PET-CT, dental and industrial non-destructive testing rooms. Uncompromised protection against scattered radiation, with industrial mechanics sized for increased door leaf weight.
Where radiation shielding is a strict technical requirement
Whether it is medical imaging diagnostics, an isotope laboratory or industrial material testing, blocking harmful ionising radiation protects human lives. In a radiation shielding door, even the smallest joint error or radiation gap can represent a critical audit and health risk.
The most important feature of professional X-ray doors is the uninterrupted lead shielding chain. It is not enough to line only the door leaf with lead; the frame system, wall connection, lock area and hinge details must also overlap with the radiation shielding built into the wall structure.
The presence of lead lining significantly increases the weight of the door system. Standard architectural hardware cannot withstand this load over the long term, so we use heavy-duty industrial hinges, rails and massive load-distributing steel frame systems.
On request, radiation shielding can also be combined with hermetic sealing, allowing one hybrid door system to maintain cleanroom pressure cascades while providing radiation therapy protection.
Technical details for perfect shielding
Closed lead shielding chain
The lead lining of the door leaf overlaps with the specially designed lead-lined frame, so X-rays cannot pass through wall connection gaps even when arriving at an angle.
Heavy-duty hardware
To carry the extreme self-weight, we use industrial hinged-door or sliding-door hardware so the structure operates safely over the long term without sagging.
Hygienic stainless steel surface
The door leaf cladding can be made from robust brushed stainless steel, which is easy to clean in industrial, laboratory and healthcare environments.
Design based on function and available space
Classic radiation shielding doors
For standard X-ray laboratories, dental practices and diagnostic rooms. Built with reinforced steel frames, heavy-duty hinges and optionally with lead-glass vision panels.
Space-saving sliding systems
For larger equipment, CT, PET-CT or industrial inspection environments. Built with high-load rail systems and available with manual or automatic operation.
Hermetic radiation shielding doors
For hybrid operating theatres and special treatment rooms where radiation shielding must be combined with cleanroom, gas-tight or pressure-cascade-supporting sealing.
Technical and material quality parameters
The exact layer structure, lead lining, hardware and operating method are always determined according to the radiation protection plan, wall opening size and room function.
| Pb equivalence | From 0.5 mm to 2.0 mm Pb, configured according to the project-specific radiation protection plan |
| Door leaf structure | Solid core with integrated lead foil insert, with two-sided HPL or stainless steel cladding |
| Frame structure | Reinforced, lead-lined frame designed for gap-free wall connection |
| Hardware | Weight-rated industrial hinges or heavy-duty sliding-door rail system |
| Automation | Special-torque electromechanical sliding-door or hinged-door drive with obstacle detection |
| Lead glass | Optional flush-mounted protective glass with Pb equivalence matching the door |
| Safety functions | Closed-position feedback, interlock preparation and door status signal connectable to the control system |
Where is a qualified radiation shielding door required?
The separation and shielding of radiation protection zones must always be designed according to the applicable radiation protection plan, equipment performance, room function and operating environment.
For safely separating X-ray, CT and PET-CT examination rooms and the related operator areas.
For separating panoramic X-ray and CBCT rooms where protection of waiting, treatment or staff zones is a key requirement.
For oncology treatment rooms and operating theatres where diagnostic or therapeutic radiation sources are used.
For factory X-ray cabins and metal industry, automotive or aerospace inspection rooms where higher shielding performance is required.
Precision from radiation protection plan to qualification
Plan processing
Based on the radiation protection plan, we define the required lead thickness and Pb equivalence.
Mechanical sizing
According to the weight of the lead insert, we calculate the door leaf mass and select the appropriate hinge, rail system or motor.
Custom layer production
We integrate the lead shielding into the frame and door leaf without gaps, then create the final surface finish.
Professional installation
At wall connections, we ensure shielding overlap so that the complete door system forms a closed protective chain.
Professional answers before planning begins
What is Pb equivalence?
Pb equivalence indicates how many millimetres of pure lead sheet the radiation absorption capacity of a given structure corresponds to. This value is defined by the radiation protection plan.
Can such a heavy door be automated?
Yes. With properly sized industrial electromechanical automation, even a heavy radiation shielding sliding or hinged door can be operated safely and conveniently.
Can the door be connected to the X-ray equipment control system?
Yes. Opening sensors or closed-position feedback can be integrated into the door and transmitted as an interlock signal to the equipment control system.
Can it be installed into an existing wall opening?
Yes, provided that the receiving structure has suitable load-bearing capacity and radiation protection design. Shielding overlaps at existing wall connections require special attention.
