Segmented Gamma Scanner is one of the most important non-destructive assay instruments, which is used to quantify radioactive isotopes in low or median-density matrix. The present research concerns in its physical design. The mainframe consists of three parts, such as transmission assembly, sample position system and detector assembly. Transmission source shielding will be made from tungsten-ferronickel; this
