| Standard high-density barite board | 12.5 mm (1/2 in) | 2.20–2.60 g/cm³ | 27.5–32.5 kg/m² | 5.6–6.7 lb/ft² | Approximately 0.30–0.60 mm Pb | May be produced to applicable gypsum-board requirements when the manufacturer declares compliance; shielding performance is additional to ASTM C1396. | Product data sheet, density report, thickness tolerance, and radiation attenuation test report identifying the test kVp. |
| Enhanced shielding board | 15.9 mm (5/8 in) | 2.20–2.60 g/cm³ | 35.0–41.3 kg/m² | 7.2–8.5 lb/ft² | Approximately 0.40–0.80 mm Pb | 5/8-inch gypsum-board thickness is commonly recognized in ASTM C1396 product categories; verify the specific barite-core construction. | ASTM C1396 declaration, ASTM C473 physical-property data where applicable, and project-specific shielding calculations. |
| Heavy-duty radiation shielding board | 19.0 mm (3/4 in) | 2.30–2.80 g/cm³ | 43.7–53.2 kg/m² | 9.0–10.9 lb/ft² | Approximately 0.50–1.00 mm Pb | Thickness and edge details should be checked against the selected ASTM C1396 board type and the tested installation system. | Independent attenuation report, compressive-strength data, screw pull-through data, and installation instructions. |
| Maximum-thickness shielding board | 25.0 mm (approximately 1 in) | 2.30–2.80 g/cm³ | 57.5–70.0 kg/m² | 11.8–14.3 lb/ft² | Approximately 0.70–1.30 mm Pb | Confirm whether the product is classified as gypsum board under ASTM C1396 or requires a project-specific material approval. | Full technical submittal, structural support review, handling instructions, and attenuation values at the actual operating energy range. |
| Supplier and Product Qualification Criteria |
| Dimensional consistency | Thickness tolerance declared by the manufacturer | Uniform density across the panel | Weight should be calculated from measured density and thickness | Non-uniform density can reduce predictable shielding performance | Review applicable dimensional and physical-property requirements under ASTM C1396/C1396M | Require batch identification and quality-control records |
| Edge and joint design | Tapered, square, or reinforced edges | Barite core must remain continuous at edges | Joint treatment must not create an unshielded gap | Lead equivalence applies only to the tested assembly and joint configuration | Installation should also be reviewed against ASTM C840 principles where applicable | Obtain joint details, fastener spacing, sealant requirements, and penetration-treatment drawings |
| Framing and support | Use framing rated for the calculated dead load | High-density panels are substantially heavier than ordinary gypsum board | Allow for panel, framing, fastener, and finish loads | Structural movement can open joints and compromise shielding continuity | Coordinate with ASTM C645 framing requirements when steel framing is used | Require a load calculation and maximum permitted stud spacing |
| Radiation test reporting | Test energy must be stated | Report material density and specimen thickness | Include measured rather than nominal values where available | Lead equivalence is energy-dependent and is not a universal constant | ASTM C1396 does not by itself establish radiation shielding equivalence | Accept only reports identifying beam quality, geometry, measurement method, and uncertainty |
| Fire and moisture performance | Verify the complete wall assembly | Core composition may affect handling and finishing | Do not infer fire rating from panel thickness alone | Radiation shielding and fire-resistance ratings are separate properties | Request the applicable tested assembly rather than relying on a board-only claim | Require fire-rating evidence, SDS, storage instructions, and indoor-use limitations |
