● 1 in. Provides 0.4 in. Lead Equivalent ● Non-Hardening, Will Not Dry Out, Reusable, Lead Free ● Provided in 10 lb Cans
Shieldwerx SWX-262 Gamma Putty is a malleable gamma radiation shielding clay that contains no lead. Gamma Putty contains high-density bismuth that is uniformly distributed throughout the binder material to insure there are no gamma streaming paths. The additive is elemental bismuth, 90% by weight, and the material will not dry out to form a powder. It is supplied in chunks that are readily pliable by hand and holds its shape after placement. Typical applications include temporary gamma radiation shielding during reactor maintenance, shielding for cable tray penetrations, industrial radiographic film masking. Disposable gloves are recommended when handling as the putty is quite sticky. |
