METHOD FOR DETERMINING THE ISOTOPE RATIO OF FISSILE MATERIAL

摘要

A method for determining isotope ratio of fissile material having a main isotope and at least one impurity isotope, including: measurement of net areas, at respective energies, of gamma peaks of the fissile material; measurement of the reference total absorption efficiencies at the energies; calculation of the total efficiency transfers of the fissile material; and calculation of the isotope ratio of fissile material.
