Redesign of the software for the Unified system of individual dose control of the citizens and radiation-hygiene passportization

Radiation dose monitoring and recording serve as an effective tool for ensuring the radiation safety of the population of the Russian Federation. The informational foundation for this monitoring and recording is provided by the Unified system of individual dose control of the citizens and radiation-hygiene passportization of organizations and territories. The software for these systems was developed in the early 2000s and is now obsolete, both morally and technologically. The aim of this work is to identify possible approaches to improving the software. Materials and Methods: An analysis of the shortcomings of the existing software was conducted, and promising directions for its redesign were identified, taking into account economic, material-technical, and time constraints. Results and Discussion: A software prototype was developed using Python and SQLite. Conclusion: The developed prototype provides cross-platform compatibility, portability, the capability for integration with regional and federal databases, and a high level of information security.
