Central Registers And Databases Maintained in Radiation Protection

Over the course of 1997 – 2004 the State Office for Nuclear Safety developed management tools for the state records systems as stipulated by Act No. 18/1997 Coll.. This concerns the central evidence (registers) of professional exposures, ionizing radiation sources, license holders, and the reporting entities and population exposure in the application of ionizing radiation sources in medicine as well as population exposure due to natural radiation sources.

Central Register of Occupational Exposure (CRPO)

This registry is presently fully and routinely utilized by the State Office for Nuclear Safety. The registry includes data processing tools from particular suppliers designed for updating their own database. The registry enables information retrieval on recorded personnel, collective information sorted by particular workplaces or professional groups, and collective information in summary statistical outputs according to selected parameters. The records are kept in the way that corresponds to the requirements for personal data protection. In 2003 the records were extended with the records of radiation ID cards issued to external personnel.

Register of Ionizing Radiation Sources (RZ)

Since 2000 this application has routinely operated and enables the retrieval and display of historical data on recorded sources and includes administrative tools of the scope of separate sealed radionuclide sources, as well as the facilities containing the sources and ionizing radiation generators. It is continuing to develop, and the registry will also include the records and evaluation of long-term stability tests. The data required from license holders into the state record system are the subject of the annex to Decree 307/2002 Coll. and SÚJB distributes registration cards of particular types of the sources for reporting purposes. From 2002, those holders permitted to import, export, distribute and produce sources have been under obligation to send the summaries of the sources distributed by them to the Office twice a year. These summaries are subsequently used to inspect the completeness of the central records of ionizing radiation sources. From 2002, data from the registry of sources concerning the location of radionuclide sources have also been provided for the purposes of Fire Rescue Brigade. In 2003, data on workplaces with open ionizing radiation sources were added to the records.

Register of License Holders and Reporting Entities (RDPO)

In 2000 implementation commenced of the Registry of License Holders and Reporting Entities as an integrating tool of the registries operating at the State Office for Nuclear Safety. The Central Registry of Occupational Exposure and the Registry of Ionizing Radiation Sources are connected to the Registry of License Holders and Reporting Entities, as are the Registry of Nuclear Materials and the Registry of Decisions. In 2003 the Registry of the data on executed inspections was completed – Registry of Inspections, which was fully put into operation in 2004.

In 2004, the presentation of data of the above-mentioned registers was prepared on the SÚJB Internet pages. In 2005, the license holders will be enabled, through the controlled access, to check the details on them kept in the SÚJB databases to the maximum possible extent.

Central Database of Medical Exposures

This database contains data provided by the General Health Insurance Company based on the application of the State Office for Nuclear Safety and is kept separately without a link to the above registers. The processing of the data provided by the General Health Insurance Company makes it possible to detect frequencies of particular types of examinations in the fields of X-ray diagnostics and nuclear medicine for selected age groups of patients and also depending on their sex. In case of nuclear medicine, the quantity of applied pharmaceutical can be assigned to each examination. The last period of processed data is the year 2002. The data are anonymous as per persons and workplaces.
