Last update : February 2, 2017 National competent authoritiesNational competent authorities: Concerning occupational exposure the Ministry of Social Affairs and Employment and its Inspectorate SZW are the competent authorities. The ANVS (Authority for Nuclear Safety and Radiation Protection) is also involved in occupational exposure when it comes to overseeing radiation protection of workers in nuclear facilities. National legislative frameworkMain texts of the national regulation: The legislative and regulatory framework concerning occupational radiation protection is laid down in a royal decree (http://wette.overheid.nl/BWBR0012702). The protection of workers against the hazards arising from ionising radiation is laid down in a ministrial decree (http://wetten.overheid.nl/BWBR0034241). Provisions more stringent than the Directive EURATOM: YesPersonal dosimetrys is mandatory for category B workers. Effective dose limit of 20 mSv each year rather than 20 mSv per year averaged over 5 years. National dose registerNational body responsible of national statistics: The national dose register (http://www.ndris.nl) is operated under the mandate of the ministry of Social Affairs and Employment. Types of recorded data: Passive dosimetryInternal dosimetry: commited doses onlyAircrew external dosimetryData sender to the register: All dosimetry servicesDoses received in another country: YesDirect access to the register data: AuthoritiesOther access to the register data: WorkersAuthorities Radiation passbookWorkers with radiation passbook: Only specific group of workersTo enable adequate protection every Dutch radiation worker who is going to undertake activities in a controlled area outside the Netherlands must have a radiation passbook. The passbook is issued on request by the operator of the national dose register (NDRIS). Radiation passbook centralisation: Yes Approved dosimetry servicesApproval of dosimetry services: Approval for recognition of the dosimetry services is given by the responsible authority. Approved dosimetry services: Two approved dosimetry services are operating in the Netherlands. Both services hold a ISO 17025 accreditation.

Internal exposure monitoringIn vivo measurements: Whole body counting Internal commited dose assessment: Health physics expert Recording level for internal commited dose: All doses over 0 mSv Radon exposureMonitoring radon exposure: Members of the public can request a radon detector from commercial organisations such as NRG (http://www.nrg.eu). It is recommended that the radon measurements should last for a minimum of 3 months. A reference level of 100 Bq/m3 is proposed by the authority.
