Abstract

The article presents a comparison of three methods of noise reduction in the gamma spectrum evaluation. The distortions’ elimination in this way can lead to increasing accuracy of elements content and identification of radionuclides. The proposed methods were applied for data obtained from the scintillation spectrometer for standards and samples of ash from coal power plants. For presented methods, the measurement system calibration and determination of the content of radioactive elements are described.
