  • Radioactivity evaluation method and radioactivity evaluation system
    Patent number: 8853638
    Abstract: According to an embodiment, a radioactivity evaluation method has: a first input step; a selection step in which the calculating section selects a representative neutron energy spectrum and a representative neutron fluence rate; a second input step; an radioactivity calculating step in which the calculating section calculates quantities of the radioactivity that correspond to the representative neutron energy spectra and the representative neutron fluence rates; a data storing step; a nuclide-by-nuclide radioactivation reaction rate calculating step in which the calculating section calculates a radioactivation reaction rate of each nuclide based on the neutron energy spectra at the position of each of the object sections; an object-by-object adding-up step; a nuclide determining step; and an object position determining step.
