Employees from the Laboratory of Neutron Physics at JINR received a certificate of state registration of a new program for verification of processed gamma-ray spectra and correction of radionuclide libraries. The development allows scientists to interactively verify the results of complex spectrometric measurements, minimising the chance of errors in the final data.
The new software is intended primarily for specialised laboratories using the method of instrumental neutron activation analysis (INAA). This highly sensitive analytical method is widely used today in environmental biomonitoring, materials science, biological, geological, and archaeological research, as it allows determining the elemental composition of natural and synthetic samples with high accuracy.
The new software greatly facilitates the work of researchers by automating the process of verifying and correcting the results of the identification of radionuclides in gamma spectra. The system highlights statistically unreliable data using colour indication and allows the user to visually monitor the reliability of the identification of each radionuclide, quickly selecting positions that require additional analysis. To check the correctness of the processing of total absorption peaks, it is possible to view sections of the gamma spectrum.
The key element of the program is an iterative verification algorithm: based on decisions about the presence or absence of radionuclides in the gamma spectrum, the working library is automatically adjusted and the identification results are recalculated. The cycle repeats until the entire set of identified radionuclides is recognised as trustworthy. This functionality significantly speeds up the analysis of processed gamma-ray spectra, which makes the program especially effective in conditions of mass INAA.
The authors of the development are Vladimir Galustov and Omari Chaligava, employees of the Group No. 1 of Gamma Spectrometry at the Sector of Neutron Activation Analysis and Applied Research of the Laboratory of Neutron Physics at JINR. The application is written in the C# programming language. It is fully compatible with personal computers using Windows 10 and up. The program size is 5.21 MB.
The certificate of state registration of the program was received by the Joint Institute for Nuclear Research on 14 April 2026.
Congratulations to the FLNP scientists on receiving state registration!
