  • Publication number: 20010048730
    Abstract: Two gamma-rays emitted simultaneously from each of the radionuclides in a radioactivated sample are simultaneously measured with a multiple gamma-ray detector assembly to construct a two-dimensional matrix rather than a one-dimensional spectrum, and the individual nuclides are measured in a completely separate form without performing any artificial operation such as chemical separation.
