BS 4513:1969

This British Standard specifies requirements for the design of the basic bricks of two systems of lead shielding bricks.

It does not give dimensional details of functional units such as window assemblies, aperture bricks, etc., although Figure 6 gives diagrammatic illustrations of the various functional units commonly in use.

The scope of this standard does not include advice on methods of constructing shielding barriers from the bricks, or on the shielding thickness required. Advice on the former may be obtained from the manufacturers of the bricks, and advice on the latter from the Radiological Protection Service.

Specification with metric dimensions for two systems of interlocking lead bricks for building permanent or temporary shielding walls, including numbering system with illustrations, and schedule for ordering purposes.
