This Salt Cellar lead block is 4cm wide, 7cm long, and 5cm thick.

We offer a large assortment of Lead Shielding Blocks for cobalt and linear accelerators. Blocks are made of gravity cast antimonial lead resulting in harder blocks that resist scratching and corner breakage. All surfaces are machined flat, square and smooth and are finished with a tough polyurethane paint. The bottom of each block is covered with thick vinyl to minimize scratching of the surface on which they are placed.
Blocks for use with a treatment tray can be studded with stainless steel bolts. The protruding stud of each block has a wing nut which secures the block to the treatment tray. This is necessary for rotational and angular treatments.
