Abstract

Abstract

The decay dynamic equations of two daug hters are resolved as initial activities of daughters are not zero, and calculation formula of activities for measuring uranium and thorium series of disequilibrium using spectrosopy is given.²³⁸U,²³⁴Th,²²⁶Ra,²²²Rn,²²⁸Ra,²²⁸Th,²²⁴Ra,²¹²Pb,²¹⁰Pb and ⁴⁰K in two sediment samples are determined as application.
- uranium series,
- thorium series,
- disequilibrium series,
- analysis of γ-spectrum
