Abstract :
In the present work a HPGe detector is investigated, refined and checked for absolute measurements of Nuclear Material (NM). All detector parameters were determined by different experiments. The detector model was validated by comparing calculated and experimental absolute full energy peak efficiency at different gamma line energies using point and SNM sources. Also an absolute method was used to estimate uranium contents in some NM samples. NM was measured by an absolute method through combination of experimental measurements and Mont Carlo. This study provides a reliable accounting for and control of nuclear material for a State to be able to meet its international nuclear non-proliferation obligations on the basis for the application of IAEA safeguards.
