Abstract

Abstract

The decay dynamic equations of two daughters were resolved as initial activities of daughters are not zero, and gave calculation formula of activities for measuring uranium and thorium series of disequilibrium using γ-spectroscopy. ²³⁸U, ²³⁴Th, ²²⁶Ra, ²²²Rn, ²²⁸Ra, ²²⁸Th, ²²⁴Ra, ²¹²pb, ²¹⁰pb and ⁴⁰K in two sediment samples were determined as application.
