Last update : December 31, 2018 National competent authoritiesNational competent authorities: Regulatory bodies responsible for governmental administration and supervision in the field of radiation protection are Slovenian Radiation Protection Administration (SRPA) and Slovenian Nuclear Safety Administration (SNSA). SRPA is an independent regulatory body within the Ministry of Health. SRPA is a competent authority for surveillance of radiation sources used in medicine or veterinary, radiation protection, medical surveillance and education and training of exposed workers, records on personal doses of exposed workers, protection of general population, general monitoring of food and drinking water, systematic radon surveillance and approval of radiation protection experts, dosimetry services, medical physics experts and medical practitioner. Equivalently SNSA is an independent body within the Ministry of Agriculture and the Environment. SNSA acts as the national regulatory authority for nuclear safety, surveillance of radiation sources others than those used in medicine and veterinary, for monitoring of radiation in the environment and in the vicinity of nuclear facilities, for waste management and for transport. National legislative frameworkMain texts of the national regulation: General legislative framework in radiation protection and nuclear safety is given by Ionising Radiation Protection and Nuclear Safety Act (OJ RS, No. 76/17; IRPNSA in further text) and underlying legislation. It fully reflects the requirements of the Euratom 59/2013 Directive. IRPNSA is a general law describing fundamental measures that are necessary in order to provide radiation protection of environment, population, workers and patients and safety measures for nuclear and radiation installations. Provisions more stringent than the Directive EURATOM: Yespersonal dosimetry and medical examination mandatory for category B workers, effective dose limit 20 mSv /year National dose registerNational body responsible of national statistics: Slovenian Radiation Protection Administration (SRPA) Types of recorded data: Passive dosimetryInternal dosimetry: commited doses onlyMeasurements of internal exposure to radonAircrew external dosimetryData sender to the register: All dosimetry servicesDoses received in another country: YesDirect access to the register data: AuthoritiesOccupational doctorOther:There is no direct access to CRPD. Reports are send to Slovenian Nuclear Safety Administration and to approved occupational doctors without their request. Other access to the register data: WorkersRPE/RPOEmployer Radiation passbookWorkers with radiation passbook: Only specific group of workersRadiation passbook is introduced in the beginning of 2018 for transboundary workers. Radiation passbook centralisation: Yes Approved dosimetry servicesApproval of dosimetry services: The individual monitoring of exposed workers can be performed by legal persons who are approved by Slovenian Radiation Protection Administration (SRPA). In general the accreditation according to standard ISO 17025 is the condition for an approval. Approval is granted by SRPA considering the opinion of special commission appointed by the minister of health. The commission checks the competence of experts, suitability of measuring and/or calculating methods and the content of the accreditation. However, since it is not expectable to have accredited laboratory for any method, the approval can be granted without accreditation, if the method in question is special and there is no other accredited laboratory for the same method in Slovenia. In this case the commission checks in addition the precision and traceability of measuring method, QA/AC system and technical ability of the laboratory. Approved dosimetry services: External dosimetry: Institute of Occupationla Safety (IOS). They use TLD Panasonic professional system with the minimum detection level of 0,04 mSv. IOS dosimetry service is accredited according ISO 17025 for measurements of Hp(10) and Hp(0,07) using TL dosimeters. "Jožef Stafan" Institute (JSI). They use TLD with CaF2:Mn of their own production with the minimum detection level of 0,001 mSv. The dosimetry service of JSI is accredited for measurement of Hp (10) and Hp(0,07) using TL dosimeters. JSI is approved to assess individual doses of flight crews. Dosimetric service of the Krško NPP implements dosimetry only for workers at the NPP site. They use Landauer OSL professional system with minimum detection level 0,03 mSv. The dosimetry service of Krško NPP is accredited for measurement of Hp (10) using OSL dosimeters.NPP is approved also for measurements or individual neutron doses, however they are not accredited. Internal dosimetry IOS is approved to assessed internal doses from gamma spectrometry measurement of biological samples or from contamination measurements. Laboratory is accredited for suitable methods, but in practice internal doses are seldom assessed according to these procedures. JSI is approved to assessed internal doses from gamma spectrometry measurement of biological samples or from contamination measurements. Laboratories are accredited for suitable methods, but in practice internal doses are seldom assessed according to these procedures. Radon dosimetry IOS radon laboratory . The laboratory is accredited for measurements of radon and radon daughter concentrations. Individual monitoring services: Internal dosimetry There are two whole body counters (WBC) in Slovenia which have not been accredited or approved yet: At the Krško NPP two WBCs with NaI detectors are installed. At the University Medical Centre in Ljubljana (Department of Nuclear Medicine) one WBC with Ge and NaI detectors is installed. It is intended for the control of workers and for the case of emergency. Radon dosimetry JSI radon laboratory can measure radon and radon daughter concentrations but the system has not been accredited of approved. Intercomparison measurement programs: No External exposureReference dosimetry: Passive dosimetryCategory B workers: YesPositioning of the dosemeter: Under the lead apronPassive dosimetry - Radiation background: National average is subtracted. If background measurements for a specific facility are available, this is taken into account instead. Duration of the monitoring: One month. Longer periods up to one year can be authorised by Slovenian Radiation Protection Administration (SRPA).

Assessments do not take into account actual flight plans, instead an average dose for a destination is assessed. Individual doses are then derived from number of flights to a certain destination for each individual. Internal exposure monitoringIn vivo measurements: There are two whole body counters (WBC) in Slovenia: At the Krško NPP two WBCs with NaI detectors are installed. At the University Medical Centre in Ljubljana (Department of Nuclear Medicine) one WBC with Ge and NaI detectors is installed. It is intended for the control of workers and for the case of emergency. The systems have not been accredited or approved yet. Radiotoxicological analysis: Institute of Occupational Safety (IOS) and "Jožef Stefan" Institute (JSI) are approved to assessed internal doses from gamma spectrometry measurement of biological samples or from contamination measurements. Both laboratories are accredited for suitable methods, but in practice internal doses are seldom assessed according to these procedures. Internal commited dose assessment: Approved dosimetry services Recording level for internal commited dose: Every measurable internal dose is recorded. Radon exposureMonitoring radon exposure: Individual doses of tourist workers in Karst caves are included in CRPD. Dosimetry is performed by Institute of Occupational Safety (IOS) radon laboratory. Individual doses are assessed from measurements of radon and radon daughter concentrations and occupancy times for each individual.
