Model LS0610/LS1112 lead shield is intended for use with CANBERRA HPGe detectors. It will prevent high background counts due to external sources, thus reducing counting times and improving the lower limit of detection. This shield is compact and easy to use with only 610 x 610 mm (0.37 m2) of floor space required. Transport to the final location in the building and installation are facilitated by the modular construction with no part weighing more than 100 kg (cover 112 kg) and strategically placed threaded holes for manipulation hooks. At the time of installation, the shield may be set up so that the cover opens right or left without need for clearance to the rear. The cover features a special reduced-mass design making the opening and closing of the cover less strenuous. Minimal distance between the cover and the shield body prevents direct path radiation from entering the shield cavity.
