Abstract
This paper describes a homemade lead, 15 cm-thick, cylindrical shaped shield
of a 9" x 9" NaI(Tl) gamma spectrometric well-type detector. Commercially
available lead was melted into cylindrical rings. The molds for the
cylindrical rings were made from hard-cooked beech wood which was pressed in
a sand mold to make the final mold. After cooling, the lead rings and ring
edges were sanded, transported from the foundry to the laboratory of the
Department of Physics in Novi Sad, Serbia, and assembled in the detector
shield. The total mass of the shield is 2622 kg. Some lines inside the shield
are reduced almost 200 times and the total count rate (280 keV-3000 keV) is
reduced 132.7 times.
