A software for the computer-assisted management of radiation protection and quality control of radiodiagnostic equipment is described. The code was written in DB3-plus language. In addition to some independent archives on X-ray diagnostic systems identification, it includes technical and radiation protection checks, environmental dosimetry in the controlled areas and on workers. The data can be searched through a key field and periodical radiation protection reports and action reports can be printed. The software programs can also perform some "intelligent" operations such as the calculation of controlled areas range and the classification of X-ray diagnostic systems and workers. This is done by retrieving the information from the archives. The software can be updated, revised and modified very easily, due to the non-connection of the archives. It is also very simple to connect DB3-plus archives with many other software packages to process and elaborate data. This software is the core of an integrated system we are developing to store and process data from diagnostic X-ray systems control meters and from our TLD personal dosimetry equipment.
