Desenvolvimento de um sistema integrado de gestão da dosimetria individual dos trabalhadores ocupacionalmente expostos: Agência Nacional de Energia Atómica

Abstract

This report details the development of a management system for individual dosimetry of occupationally exposed workers (TOEs) for the National Atomic Energy Agency (ANEA). It was prepared as a result of the author's professional internship at ANEA during the second semester of 2024, as part of their final course project. While manual management of dosimetry was a possibility, several international institutions emphasize its various disadvantages, such as slow processes, difficulties in auditing and data tracking, vulnerability of paper records to physical damage, limited access and consultation of data, high risk of error in manual dose calculation, poor control of reference levels, and challenges in sharing information with other departments. Considering these drawbacks, the need arose to develop an integrated computer-based system for managing individual dosimetry at ANEA, enhancing data reliability and security. The development of this system involved several stages, including meetings and interviews with ANEA technicians to understand internal dosimetry management processes, analysis of technological solutions adopted by other leading institutions, and adaptation to the specific context and needs of ANEA. From this groundwork, the system's architecture was designed, technical and functional requirements were defined, and appropriate tools and technologies were selected. The modeling phase culminated in the implementation of a robust computerized system capable of automating and integrating the entire individual dosimetry management process, aligning with regulatory requirements and significantly improving monitoring efficiency and reliability at ANEA.
