ORTEC’s high-performance, low-background Ge detector shields feature highest quality workmanship and the best materials. They include features which have evolved over years of experience in lead shield design. Options that make the shield easier to use also ensure continued smooth operation.

All ORTEC high-performance, low-background lead shields feature an 11-in.-diam X 16-in.-deep cavity, suitable for accommodating even 4-liter Marinelli beakers. A graded liner of copper and tin is provided for the suppression of lead x rays. The bulk shielding material is certified Doe Run virgin lead (4-in.-thick). The support stand and shield jacket are made from low-carbon steel. All external surfaces are finished in a durable, attractive textured polyurethane. Internal (copper and lead) surfaces are polished and coated with a clear-acrylic lacquer to minimize tarnishing of the copper liner and prevent human exposure to lead.

With each ORTEC HPLBS, the following are supplied:
1. Rigid support stand
2. Installation and maintenance manual
3. Touch-up paint
4. Assembly tools
5. Lifting eyes and lid restraint brackets
