| Shielding material composition | Barium sulfate content and gypsum-board core composition | Composition is clearly declared, traceable by batch, and supported by a technical datasheet | Technical datasheet, safety data sheet, and batch traceability records |
| Panel thickness | Available thicknesses in millimetres | Common gypsum-board thickness categories such as 12.5 mm and 15.9 mm are available, with project-specific thickness options confirmed in writing | Product catalogue, dimensional tolerance data, and sample inspection |
| Panel dimensions | Length, width, squareness, and edge profile | Dimensions match the project drawings and remain within the stated manufacturing tolerances | Dimensional inspection report and pre-shipment quality-control record |
| Bulk density and weight | Panel mass per unit area and finished-panel density | Weight is declared for structural, handling, and fixing calculations; higher-density panels are used where the design requires greater attenuation | Declared weight per square metre, density test method, and batch test results |
| Radiation attenuation performance | Measured attenuation or lead-equivalent performance at specified X-ray energies | Performance is reported for the actual panel thickness and the project’s operating voltage; no generic value is accepted without test conditions | Independent attenuation report showing kVp, beam quality, test geometry, thickness, and calculation method |
| Radiation-shielding design support | Ability to provide wall, ceiling, floor, door, joint, and penetration details | Supplier provides technical input but the final shielding design is reviewed by a qualified radiation-protection professional | Typical installation details, CAD files, joint treatment instructions, and engineering contact |
| Fire-performance documentation | Fire-resistance rating of the complete wall or partition assembly | A tested or assessed assembly is offered; the panel alone is not treated as proof of a complete wall rating | Assembly test or assessment report, installation configuration, framing details, and joint-compound specification |
| Moisture and environmental suitability | Use conditions, water resistance, storage requirements, and indoor air considerations | Product selection matches dry, humid, or controlled clinical environments; panels are protected from prolonged water exposure | Environmental limitations, storage instructions, SDS, and applicable emissions documentation |
| Installation system compatibility | Compatible studs, tracks, screws, joint compounds, sealants, and reinforcement | Complete fixing guidance is available, including screw spacing, joint staggering, and treatment of service penetrations | Installation manual, approved accessory list, and sample wall detail |
| Quality-management controls | Manufacturing inspection, calibration, nonconformance control, and batch release | A documented quality system with consistent records for density, dimensions, appearance, and composition | Quality certificate, inspection and test plan, calibration records, and corrective-action process |
| Packaging and transport protection | Pallet design, edge protection, moisture protection, and maximum stacking conditions | Packaging prevents edge damage, warping, and moisture ingress during normal transport and storage | Packaging specification, loading photographs, transport insurance terms, and damage-claim procedure |
| Production and delivery capability | Minimum order quantity, production lead time, monthly capacity, and delivery schedule | Capacity is sufficient for the project programme, with realistic lead times and written delivery commitments | Formal quotation, production schedule, capacity statement, and delivery terms |
| Technical and after-sales support | Response time, site support, replacement policy, and warranty conditions | Written warranty terms and a defined process for technical queries, damaged goods, and nonconforming batches | Warranty document, service-level commitment, contact channel, and complaint-resolution procedure |
| Total installed cost | Panel price plus framing, fasteners, handling, installation, testing, and wastage | Selection is based on verified shielding performance and total installed cost rather than panel price alone | Itemised quotation, installation assumptions, freight charges, taxes, and testing costs |
