    Graphical Abstract
    • Abstract
  • A computer code, Cool2000, is developed. It can be used to calculate the theoretical multichannels γray spectra and coincidencesumming corrections factors by simulating the processes of the natural decay series in γray spectrometry with MonteCarlo method, and to simulate the decay schemes of 24 nuclides, such as60Co,88Y,134Cs,133Ba,134Ba,95Nb,57Co,103Ru,106Ru,110Agm,124Sb,144Ce,65Zn, 58Co, 131I,140La,241Am,99Mo,166Hom,152Eu,125Sb,214Bi,212Bi(α decay series) and208T1.For a cylindrical60Co source, the coincidencesumming corrections from theoretical calculation (Cool2000) and experimental results agree with each other within the deviation ±1%. An applied method obtained the thickness of dead layer and the size of cooling finger for coaxial HPGe detector is also given.
