| Abstract: | The arithmetic for spectrum-decomposition in measurement software for low background multi-channel gamma-ray spectrometry is introduced in this paper. It is based on the facts that the complex spectra of the sample are composed of the single spectra from each component and the complex spectra can be decomposed into single spectrum for their specific activity calculations. According to this arithmetic a program is written and used in the experiment measurements. The factors influencing the measurement results are also studied. The results show that the good results are obtained when high-energy peaks are selected. |
