Last update : June 29, 2015 National competent authoritiesNational competent authorities: National competent authority in the field of personal dosimetry of exposed workers is Environmental Board, Radiation Safety Department National legislative frameworkMain texts of the national regulation: Radiation Act (entered into force 1 May 2004); Regulation of the Government No 244 of 08 July 2004: Statutes for Maintenance of the State Dose Register of Exposed Workers; Regulation of the Government N0 193 of 17 May 2004: Effective Dose and Equivalent Dose Limits for the Lens of Eyes, Skin and Extremities for Exposed Workers and Members of Public; Regulation of the Minister of Environment No 110 of 27 August 2004: Requirements for the Results of Individual Monitoring of Outside Workers and for Formalising Such Results, and for the Standard Format for the Dose Chart of Outside Workers. Provisions more stringent than the Directive EURATOM: No National dose registerNational body responsible of national statistics: Responsible controller of the State Dose Register for Exposed Workers is the Ministry of Environment and the authorized administrator is Environmental Board, Radiation Safety Department. Employer (licence holder) and IMS arrange submission of personal dose monitoring data to the State Dose Register of Exposed Workers. Access to the State Dose Register for Exposed Workers database in Internet: http://kiirgusintralive.keskkonnaamet.ee/failid/doos/er.php The data included into State Dose Register for Exposed Workers are with limited access. Data in State Dose Register shall be preserved during the entire time the exposed worker is engaged in radiation practices and until the time that person attains or would have attained 75 years of age, but not for a shorter period than 30 years after the person no longer engages in radiation practices. Types of recorded data: Passive dosimetryData sender to the register: Only several dosimetry services (e.g. only officially approved dosimetry services)EmployerDoses received in another country: YesOutside workers: Yes, the State Register for Exposed Workers include doses received by estonian workers in another country (specially märked). Direct access to the register data: AuthoritiesDirect access to the database of the Dose Register for Exposed Workers is allowed only for Environmental Board, Radiation Safety Department specialists. The occupational worker or his employer shall ask the extract from Dose Register by submitting an application. Other access to the register data: WorkersAuthoritiesRPE/RPOOccupational doctorEmployer Radiation passbookWorkers with radiation passbook: Only specific group of workersEstonian exposed workers who perform radiation activities in controlled area of outside undertaking Radiation passbook centralisation: YesState Dose Register for Exposed Workers separate part is State Dose Register of Outside Workers. Radiation Dose Passbook for estonian worker exposed to ionising radiation in controlled area outside of Estonia is issued by Environmental Board, Radiation Safety Department upon receipt of a written application . Approved dosimetry servicesApproval of dosimetry services: <p>-</p> Approved dosimetry services: 1) Environmental Board, Radiation Safety Department has an accreditation to perform measurement of personal doses of exposed workers in Estonia ( TLD); 2) North Estonia Medical Centre Foundation has an accreditation to perform measurement of personal doses of exposed workers in Estonia (DIS) Individual monitoring services: There are 2 IMS for external dosimetry in Estonia: Environmental Board, Radiation Safety Department and North Estonia Medical Centre Foundation Intercomparison measurement programs: No External exposureReference dosimetry: Passive dosimetryCategory B workers: YesPositioning of the dosemeter: Double dosimetry (under and above)Correction factors: YesPassive dosimetry - Radiation background: Environmental Board, Radiation safety Department : position of the TDL- above the apron; in case of double dosimetry effective dose is calculated by Faulkner formula. Background is subtracted during the measurement performing. North Estonia Medical Centre Foundation: the position of DIS- under the lead apron; no double dosimetry Duration of the monitoring: Environmental Board, Radiation Safety Department: for A category exposed workers-every month; for B category exposed workers- every 3 months. North Estonia Medical Centre Foundation: every month for all exposed workers.
