[en] The use of virtual reality has becoming an important tool for training purposes, with emphasis to those procedures that involve risk to professionals, as those associated with occupational exposure to ionizing radiation in nuclear medicine services. According to the basic safety standards (BSS), published by International Atomic Energy Agency (IAEA), the qualification and training of all personnel of a nuclear medicine service should be performed periodically in order to ensure its understanding and better performance of their respective duties. In face of that, this work consists in research, analysis and unification of requirements and specifications for the radiological protection of nuclear medicine workers, specifically those of radiopharmacy. To this end, a detailed study of the radiological safety and workflow related to radiopharmacy procedures is under development considering the radiological recommendations and safety standards of nuclear medicine services. As a result, it is expected a set of information that will enable the development of a virtual training environment in radiological protection for such professionals aiming the development of skills and the improvement of competencies by means of the simulation with lower cost, unlimited number of repetitions of training, without interference in the laboratory routine and the primary purpose of this work: in safe conditions.
