A system of nationwide registration of ionizing radiation sources subject to registration according to the so-called Atomic Law was develepoed for the State Office for Nuclear Safety (SÚJB). The interconnected SÚJB registers also include the Register of Professional Radiation, monitoring workers with ionizing radiation sources and their exposure. The Register of Permit Holders and Notifiers, which manages records of all permit holders within the meaning of the ”Atomic Law”, and the Register of Resolution as a tool for creation and registration of all decisions issued by SÚJB.

The basis for the application of interconnected agendas is the Agenda of Permit Holders and Notifiers. Other applications of the system are linked to this agenda and use a common centrally managed agenda that is stored in the Oracle database system.
