Storing the records

Article 42 – Records indicated in Article 41 of this Regulation are kept separately and upto date for each person, radiography device, radiation source, radiation monitoring device and dosimeters and events and accidents. Records must be ready in the inspections of the Authority experts and stored for thirty years. In case of liquidation of the work, final states of the radiation sources are determined by comparing the data found in the databases of the Authority and sources are sent to their origin under responsibility of the license holder and it is documented to the Authority.
