Lead sheet is the preferred material for radiation shielding and high energy radiation operations. Its density, high atomic number (82), and level of stability are some of its main benefits, in addition to its ease of use and availability. Lead Sheet and bricks are highly effective at shielding those exposed to radiation from gamma rays and x-rays. As a result, they are most often used in nuclear and radiation therapy applications, radioactive isotope creation, as well as for ballast weights, and counterbalances. Other uses of lead sheet and lead bricks include applications in roofing, soundproofing, and waterproofing.
Lead Sheet Sizes
Lead sheet comes in a variety of sizes and thicknesses. The most commonly used sizes include:
- 4’ x 7’ x 1/16”
- 4’ x 7’ x 1/32”
- 4’ x 7 ’x 1/8”
Mayer stocks 4 x 7 x 1/16 rolls, as it is the most commonly used thickness. Other thicknesses are available on a per request basis.
Lead Brick Types and Sizes
FLAT LEAD BRICKS
Flat or straight edge lead bricks are easily stackable and can be relocated, offering excellent radiation protection. Mayer can supply flat lead bricks with epoxy paint or powder coatings. Both types of finishes reduce environmental exposure and provide safer handling.
Though lead bricks can be customized, the most used sizes are as follows. Lead bricks are available on a custom order basis.
- 2” x 4” x 6”
- 2” x 4” x 8”
CAST INTERLOCKING LEAD BRICKS
The V-shaped tongue and groove connection of cast interlocking bricks creates an overlap of lead material at the seams. This unique locking mechanism allows for greater stability during build out, a tighter fit, and continuous, uninterrupted shielding.
Cast interlocking bricks are available in the following sizes. Lead bricks are available on a custom order basis.
- ¾” x 4” x 12”
- 1” x 4” x 12
- 1-1/2” x 4” x 12”
- 2” x 4” x 12”
- 2-1/2” x 4” x 12”
MACHINED INTERLOCKING BRICKS
Machined interlocking bricks have a U-shaped or horseshoe-shaped tongue and groove, but are similar to cast interlocking lead bricks in their benefits and applications. These types of bricks are customized to your specific project. At any length or width, the thickness can range from 1/2” to 2”. Lead bricks are available on a custom order basis.
Mayer offers lead sheet and lead bricks including flat lead bricks, cast interlocking lead bricks, or machine Interlocked bricks. Standard lead sheet orders are available for pickup at our Ferndale warehouse, and lead brick orders and special cuts of lead sheet are custom orders.
