Introduction
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.
