Shieldings for detectors, allowing a reduction in the exterior natural radioactivity values also with regard to relatively hard Gamma (K 40). They are manufactured with first quality (virgin) lead ingots, first casting with title of 99.9% of purity; dimensions and characteristics appropriated to reduce the Primary Radiation Batch-scatter phenomena. They are usually lined with tin and copper electrolyte type for secondary radiation absorption due to lead interaction. Detector fixing ring in Nylon material for NaI (Tl) probes.
On request could be supplied with support frame, lifter for Dewar (Models for Germanium detectors) and “Marinelli” glass geometry " to hold samples.
