Start Your Shielding Project

Installing X-ray equipment goes smoothly when the room, equipment, shielding, utilities, and regulatory requirements are coordinated before the install date. Most expensive problems happen when one of those items is discovered after construction has already started.

BEFORE CONSTRUCTION: INFORMATION TO COORDINATE

• Final floor plan and room dimensions. Use the latest architectural plan, with a reliable scale and room names.

• Exact equipment and generator. Provide the manufacturer, model, generator rating, tube locations, expected beam directions, and the manufacturer’s planning or installation drawings. “Similar equipment” is often not enough for a final design.

• Expected clinical use. Estimate the number and type of procedures, operating schedule, technique factors, and anticipated growth. The shielding designer will translate this information into an appropriate design workload.

• Every adjacent space. Identify occupancy beyond each wall and on the floors above and below. Include exterior areas, roofs, corridors, offices, waiting rooms, and any space whose use could change.

• Existing and proposed construction. Document wall, floor, and ceiling materials and thicknesses. Flag doors, windows, ducts, electrical boxes, plumbing, and other penetrations that may interrupt a barrier.

• Control area and equipment geometry. Confirm control booth, door, tube, detector, table, gantry, and mobile-equipment locations. Small layout changes can change a barrier calculation.

• State and local jurisdiction. Identify the project location early. Plan-review, registration, survey, inspection, and submission requirements vary by state and by project.

RECOMMENDED PROJECT SEQUENCE

1. Select the modality and equipment. Confirm the exact model whenever possible.

2. Freeze the relevant plan. Resolve room dimensions, equipment orientation, adjacent occupancy, doors, control areas, and major penetrations.

3. Complete the shielding design. The designer uses the equipment, workload, geometry, construction, and occupancy information to calculate the required barriers and prepare construction-ready documentation.

4. Complete any required pre-construction review. Some jurisdictions require shielding plans or other information before construction or installation. Confirm the applicable process before beginning shield-dependent work.

5. Build and document the barriers. The contractor should follow the shielding details, coordinate penetrations, preserve required overlaps and continuity, and document substitutions or field changes before covering the work.

6. Install the equipment. Verify that the final equipment location and orientation match the information used in the design.

7. Complete surveys or inspections when required. A qualified professional can evaluate the installed room under appropriate operating conditions and document measurements. Requirements and timing vary.

8. Finish registration and authorization steps before clinical use. The facility remains responsible for completing the steps required by its jurisdiction.

RESPONSIBILITY CHECKLIST

Facility owner or operator

• Identify the project jurisdiction and regulatory contacts.

• Approve the equipment, final layout, intended use, and schedule.

• Provide accurate workload and occupancy information.

• Complete required registrations, submissions, and operating procedures.

Architect

• Maintain the coordinated floor plan and reflected ceiling information.

• Show adjacent occupancy above, below, and around the room.

• Incorporate shielding details into the construction documents.

• Coordinate doors, windows, penetrations, and wall assemblies.

Contractor and shielding installer

• Build from the current shielding drawings and specifications.

• Verify material type and thickness before installation.

• Maintain barrier continuity at joints, corners, doors, frames, and penetrations.

• Raise conflicts or substitutions before the work is concealed.

Equipment vendor

• Provide final equipment planning drawings and technical data.

• Confirm tube, detector, table, gantry, control, and isocenter locations.

• Notify the team when the selected model or room layout changes.

• Install the equipment in the designed position and orientation.

Shielding designer or qualified physicist

• Request and document the project inputs.

• Perform project-specific calculations and prepare shielding recommendations.

• Coordinate questions with the design and installation team.

• Revise the design when material project inputs change.

COMMON COSTLY MISTAKES

• Starting framing or ordering lead before the equipment and layout are final.

• Designing from an unscaled sketch or an obsolete architectural sheet.

• Forgetting occupied space above, below, outside, or on the far side of a corridor.

• Treating an equipment replacement as automatically equivalent to the old unit.

• Moving the tube, table, gantry, control area, or door after the design is complete.

• Allowing unreviewed penetrations, gaps, or field substitutions in a barrier.

• Assuming every state follows the same submission and inspection process.

• Waiting until equipment delivery to begin shielding coordination.

MODALITY-SPECIFIC PLANNING NOTES

General radiography

Fixed tube and bucky locations, beam directions, workload, room geometry, and all surrounding occupancy matter. Floors and ceilings may be part of the shielding envelope, not just walls and doors.

CT and cone-beam CT

Requirements depend on workload, technique, scatter distribution, equipment geometry, and occupancy. Confirm the scanner model, isocenter, gantry orientation, scan volume, and expected procedure mix. Do not assume CT and CBCT rooms have interchangeable requirements.

Fluoroscopy and C-arms

Scatter radiation and procedure mix can strongly influence the design. For mobile C-arms, identify where the unit will be used, common beam orientations, and likely staff positions rather than relying on one fixed setup.

Mammography

Mammography uses different beam qualities and operating patterns from general radiography. Provide the exact unit, room layout, workload, and adjacent occupancy so the design reflects the installation rather than a generic room type.

Dental, panoramic, cephalometric, and dental CBCT

These systems have different geometries and workloads. Operator position, patient orientation, beam direction, adjacent occupancy, and whether the equipment is intraoral, panoramic, cephalometric, or CBCT should be clear.

Veterinary imaging

Animal handling can affect operator location and workflow. Document the equipment, expected procedure mix, restraint practices, room geometry, and occupancy just as carefully as for human imaging.

REQUIREMENTS VARY

This guide is general planning information. It is not a shielding calculation, regulatory approval, or guarantee of compliance. The required design inputs, submission process, construction details, surveys, inspections, and registrations depend on the equipment, facility, jurisdiction, and actual use.

START YOUR SHIELDING PROJECT

Bring Heartland Physics into the project before shield-dependent construction begins.

To get started, send the project state, current floor plan, equipment manufacturer and model, manufacturer planning drawings, expected workload, room construction, and occupancy information for every adjacent area—including above and below.

Heartland Physics can use those project details to prepare shielding recommendations and help your team coordinate the next steps.
