High Density Concrete Block
NELCO High Density Concrete Block is a space-saving shielding solution for maze and vault walls, as well as ceilings in both new facilities and vault upgrades or renovations. Available in a range of densities, these blocks are suitable for both high and low energy linear accelerator vaults and shield both gamma and neutron radiation.
For maximum shielding integrity, each block is manufactured with our proven shielded tongue and groove interlocking design. To allow for modularity (and providing a potential tax-saving benefit), HD Concrete Blocks can be put in place without mortar. For optimal space and cost savings, this product can be used in conjunction with other materials, such as N-Series Interlocking Lead Bricks, MegaShield, or lead sheet.
