Lead Lined Plywood
When the required lead thickness exceeds 1/8", lead lined plywood often is used to shield walls for radiation shielding protection.
Lead-clad plywood is available in various lead thickness and heights. It is attached to walls using techniques designed to ensure a continuous lead sheet to the shielding height specified in the order. Plywood is bonded to the lead sheet, providing good support during installation.
Lead sheets are 48" wide on 48" plywood. Two-inch wide battens are used to shield all joints. Panels typically are mounted with conventional drywall screws.
All cutouts in the lead-lined drywall for wall switches, outlets, etc., must be shielded with sheet lead to prevent leakage.
