Twenty years of inspection interventions in Slovenia

After the Dijon Conference in 1998, Slovenia upgraded emergency response systems giving attention to orphan sources. It followed the European Union legislation, e.g. Council Directive 2013/59/EURATOM, and international experiences. The upgrading includes, among others, 24h on duty Slovenian Nuclear Safety Administration (SNSA) service, reporting of incidents and accidents and installation of radiation monitors. The SNSA established already in 2002, the SNSA Database of Interventions with records of all events requiring prompt inspector actions, i.e. interventions. Today, the SNSA Database contains records on about 300 cases. Despite the fact that each intervention is unique, several types of interventions might be identified, e.g. interventions related to handling sources or radioactive waste, transport and false alarms. About 20% of interventions are related to NORM, whereas about 30% are false alarms. The SNSA Database is a tool used to implement a graded approach as well as an optimization of radiation protection in SNSA response to interventions.
