Key Takeaways:
- Start With the Shielding Design: A qualified radiation shielding evaluation establishes the protection required for each applicable barrier before materials are ordered.
- Proper Installation Is Essential: Lead-backed drywall, doors, windows, joints, fasteners, and penetrations must be installed to maintain the shielding continuity specified in the design.
- Coordinate Before Closing Walls: Electrical, mechanical, plumbing, and framing work should be coordinated with the shielding requirements before finishes conceal critical details.
- Document Shielding Installation: Photographs and installation records help verify concealed construction details and support project quality control.
- Lead Glass Pro Offers Nationwide Installation: Our CRSI-certified installers provide professional radiation shielding installation services backed by applicable warranty and compliance protections.
Installing radiation shielding in an X-ray room involves more than attaching lead-lined drywall to walls.
A properly coordinated project requires shielding design, material selection, framing preparation, specialized installation, documentation, and any required post-installation verification.
Each stage affects the next. Incorrect material specifications, poorly coordinated openings, or unaddressed penetrations can create expensive problems after walls are finished.
At Lead Glass Pro, we manufacture and supply radiation shielding materials, including lead-backed drywall, X-ray lead glass, complete lead-lined window assemblies, and lead-lined doors.
We also provide professional radiation shielding installation services nationwide using CRSI-certified installers.
This guide explains the major stages of the installation process, from the initial shielding evaluation through final project verification.
Step 1: Obtain the Radiation Shielding Design
Before selecting or ordering shielding materials, the project team should establish the required radiation protection.
A qualified medical physicist, health physicist, or other appropriately qualified shielding professional evaluates the room and determines the necessary barrier protection.
Depending on the equipment and jurisdiction, a formal shielding report may be required.
What Does the Shielding Evaluation Include?
The shielding professional considers factors such as:
- Type of radiation-producing equipment
- Equipment operating characteristics
- Expected workload
- Primary and secondary radiation barriers
- Room dimensions and equipment placement
- Distance to adjacent occupied areas
- Occupancy of surrounding spaces
- Existing construction materials
- Applicable radiation protection requirements
The resulting design identifies which barriers require shielding and the required protection for each.
Does Every Wall Require Lead Shielding?
Not necessarily.
Some walls may require lead-backed drywall, while others may provide sufficient protection through existing construction.
Ceilings, floors, doors, and observation windows are evaluated based on their individual exposure conditions.
This is why material quantities should be determined from the approved shielding requirements rather than assuming every surface needs the same lead thickness.
Important: Lead Glass Pro supplies and installs radiation shielding products according to confirmed project specifications. Shielding requirements must be established by an appropriately qualified professional.
Step 2: Review the Room Layout and Coordinate Construction
Once shielding requirements are established, the project team should review the architectural drawings and construction details.
This stage helps ensure the shielding materials can be installed correctly without interfering with framing, doors, windows, electrical systems, or mechanical equipment.
Wall Framing and Panel Layout
Lead-backed drywall is commonly supplied in 4-foot-wide panels.
Framing and panel layout should be coordinated to provide proper support and allow the required shielding details to be installed.
The project team should verify:
- Wall dimensions and shielding heights
- Panel orientation and layout
- Stud spacing and structural support
- Shielding continuity at corners
- Transitions between shielded and unshielded construction
- Ceiling and floor intersections
- Locations of electrical and mechanical penetrations
Panel layout should follow the approved construction documents and manufacturer's installation instructions.
Door and Window Openings
Lead-lined doors and radiation-shielded windows require properly coordinated rough openings.
Lead Glass Pro's Rapid Install™ window systems feature factory-installed glass and adjustable frames designed to simplify installation across a range of wall thicknesses.
Before framing an opening, confirm the manufacturer's required rough opening dimensions rather than assuming the nominal window or door size is the rough opening size.
For Lead Glass Pro window assemblies, rough opening requirements should be verified against the specific product documentation.
Electrical and Mechanical Coordination
Penetrations through shielded barriers must be addressed before walls are closed.
Common examples include:
- Electrical boxes
- Plumbing pipes
- HVAC ductwork
- Conduit penetrations
- Medical equipment connections
- Access panels
- Other wall-mounted devices
The required shielding details depend on the approved design and the type of penetration.
Coordinating these locations early helps prevent costly modifications after installation.
Step 3: Select and Order Radiation Shielding Materials
Once the shielding design and construction details are confirmed, materials can be ordered.
Each product must provide the required radiation attenuation and be compatible with the intended construction.
Lead-Backed Drywall
Lead-backed drywall combines gypsum wallboard with factory-applied sheet lead.
Lead Glass Pro offers multiple lead thicknesses and panel configurations to accommodate different shielding requirements.
Standard lead-backed drywall packages include:
- Factory-applied sheet lead
- One 2" wide lead batten strip per panel
- 50 lead discs for fastener coverage
Custom configurations are available for projects requiring different shielding heights or specifications.

Radiation Shielding Accessories
Additional shielding components may include:
- Lead batten strips
- Lead discs
- Lead corners
- Electrical box shielding
- Lead sheet
- Shielded access panels
These components help maintain shielding continuity at joints, fasteners, penetrations, and construction transitions.
Step 4: Prepare the Job Site and Materials
Before installation begins, the contractor should confirm that the site is ready to receive and handle shielding materials.
Delivery and Material Inspection
Lead-backed drywall and lead-lined door assemblies can be substantially heavier than conventional building materials.
Delivery planning should account for:
- Shipment weight and packaging
- Unloading equipment
- Access to the building
- Storage space
- Material handling requirements
- Protection from damage and moisture
Inspect materials upon delivery and document visible damage or shortages promptly.
Record appropriate delivery exceptions and follow the supplier's freight claim procedures.
Lead Handling and Worker Safety
Lead is a hazardous material, and cutting or disturbing lead-containing products can create exposure risks.
Installation teams should use appropriate handling methods, engineering controls, hygiene practices, and personal protective equipment based on the task and applicable safety requirements.
Work practices should minimize the generation and spread of lead dust or debris.
Employers should evaluate applicable OSHA requirements and ensure workers are appropriately trained.
Step 5: Install Lead-Backed Drywall
Lead-backed drywall installation requires careful attention to shielding continuity.
Although the panels resemble conventional drywall, the lead layer must remain continuous across the areas requiring radiation protection.
Panel Positioning and Orientation
Lead-backed drywall should be installed according to the manufacturer's instructions and approved construction details.
For Lead Glass Pro's standard installation method, panels are positioned vertically with the lead layer facing the wall cavity.
Installation generally begins at a corner and proceeds across the wall.
Panel layout must accommodate the specified shielding height, wall intersections, openings, and required joint treatments.
Lead Batten Strips at Panel Joints
Lead batten strips are used to maintain shielding continuity between adjacent lead-backed drywall panels.
The strips must be installed in the locations and configurations required by the approved shielding details.
Lead Glass Pro's standard drywall packages include one 2" wide batten strip per panel.
The purpose of the batten is to provide the necessary lead overlap or backing at the panel joint so that the shielding barrier remains continuous.
Fastener Shielding
Fasteners penetrate the drywall and may affect the continuity of the lead layer.
Lead discs or other approved details are used where required by the shielding design and manufacturer's installation instructions.
Lead Glass Pro includes 50 lead discs with each standard lead-backed drywall panel.
Fastener coverage should be verified before finishing begins.
Corners and Wall Intersections
Corners and wall intersections require appropriate shielding details to maintain continuity between adjacent barriers.
These details may involve overlapping lead sheets, lead corner strips, or other approved methods.
The required construction should be established before installation.
Electrical Boxes and Penetrations
Electrical outlets, junction boxes, plumbing, and mechanical penetrations can interrupt the shielding layer.
Where shielding is required, these openings must be treated using approved details that maintain the specified radiation protection.
Lead-backed electrical box protection and other specialized shielding accessories may be used where appropriate.
Step 6: Install Lead-Lined Doors and X-Ray Windows
Doors and windows are important parts of the radiation shielding system.
They must provide the required protection and integrate correctly with the surrounding shielded walls.
Installing Lead-Lined Window Assemblies
A complete lead-lined observation window consists of radiation-shielded glass and a compatible lead-lined frame.
The frame must maintain the required shielding continuity with the adjacent wall construction.
Lead Glass Pro's Rapid Install™ systems are designed to simplify this process through factory-glazed assemblies and adjustable frame construction.
Installers should verify:
- Correct window dimensions
- Required lead equivalency
- Proper rough opening
- Frame compatibility with wall thickness
- Required lead overlaps
- Secure attachment
- Applicable safety glazing requirements
Installing Lead-Lined Door Assemblies
Lead-lined doors must be installed with compatible frames and hardware details that preserve the required radiation shielding.
Complete pre-hung assemblies can simplify installation by providing coordinated components.
Installers should verify:
- Door and frame lead equivalency
- Correct opening dimensions
- Proper frame installation
- Shielding continuity at the perimeter
- Hardware preparation and compatibility
- Door swing and clearances
- Applicable fire-rating requirements
A lead-lined door alone does not necessarily provide a complete shielding solution if the frame or surrounding construction is improperly specified or installed.
Step 7: Inspect and Document Shielding Before Finishing
Before concealed shielding details are covered, the installation team should perform a quality-control inspection.
This is one of the most important opportunities to identify and correct installation deficiencies.
