There have been several “game changers” in the healthcare profession including antibiotics and advanced vaccines. Nuclear medicine has been particularly valuable as a diagnostic tool and treatment for certain forms of cancer. It’s safe for patients in small amounts, but riskier for the technicians who are exposed to the radiation on a routine basis. That’s why it’s so important to make sure that they’re protected with proper radiation shielding protocols.

National Custom Hollow Metal is one of America’s leading lead door manufacturers, and our TrustShield lead-lined doors and frames offer the ultimate protection from radiation contamination.TrustShield Lead Lined doors are available in 16, 14 or 12 gauge galvanneal or 16, 14 or 12 gauge stainless steel construction with a continuous sheet of lead from 1/32″ thick up to 1/8″ thick, laminated to the door skin and a sheet of high density polystyrene. The lead sheet extends the full width and height of the door, with the thickness of the lead shielding to be equal to that of the adjacent wall. Lead lined doors can be built at 4′ 10 1/2″ x 12’0″ with 1/16″ lead and 4’10’/2″ x 8’0″ with 1/8″ lead, and all doors have continuous 14 gauge channels installed around the perimeter as reinforcement to ensure years of trouble-free service. TrustShield doors and frames can be manufactured with UL or Warnock-Hersey fire resistance labeling up to 1-1/2 hours with maximum thickness of 3/32″.
