Lead Lined
Plywood
Lead lined plywood is typically utilized in
applications requiring a lead thickness in excess of 1/8”. Any
grade of plywood including fire-treated is available. Plywood
panels are pressure laminated with a permanent adhesive to
unpierced sheet lead and arranged to provide effective lead
shielding through all joints. Depending on required lead
thickness (determined by a health physicist), panels can be
reduced in size to facilitate installation.
Standard
Installation:
-
Place leaded side of plywood against studs.
-
Drill pilot holes for screws to prevent
deformation of lead.
-
A minimum lead overlap of one inch is
required at all joints and corners.
-
Extend lead overhang at least one inch into
all frames or openings.
-
Panels can be sized to match stud widths.
This will require the installation of a batten strip along the
seam.
-
The area between the batten strips can be
filled with non-leaded plywood to facilitate the installation
of the finished wall.
-
Install lead over or behind all
penetrations, cuts, or punctures to ensure continuity of
radiation shielding.
