List of authorised dosimetry services

Dosimetry services (Art. 20)

The dosimetry service sets the doses to which workers subject to personal radiological monitoring can be exposed and, in cooperation with the establishment or, in the case of outside workers, with the employer, records the doses to which they are actually exposed in the central dosimetry register kept by the radiation protection division (Division de la radioprotection - DRP) of the Health Directorate (Direction de la santé).

Use of a dosimetry service is subject to prior ministerial authorisation. Authorisation is granted subject to the dosimetry service having:

• been accredited in its field of expertise by the competent authority of the country where the service is established, with such accreditation covering all of the measurement techniques employed by the service;
• a radiation protection expert on its staff;
• an ongoing training programme that provides for at least 8 hours of training in measurement techniques, dosimeter calibration and quality assurance for a dosimetry service, every two years, for anyone who is responsible, according to the terms of the accreditation, for quality assurance for dosimetry results.

Authorisation is granted for a renewable period of five years, and specifies the dosimetry service's field of expertise, based on the measurement techniques for which the service is accredited.

Accreditation

Accreditation is granted by the Luxembourg Office for Accreditation and Monitoring (Office luxembourgeois d’accréditation et de surveillance), if the dosimetry service:

• applies the ISO/IEC 17025 standard on the general requirements for the competence of testing and calibration laboratories;
• participates, at intervals not exceeding three years, in verification of performance controls through a European inter-comparison on the quality of the results of dosimetric measurements; and
• has a quality assurance programme covering the calibration and verification of dosimeters, including their dosimetric performance features, the management of uncertainties, the performance of comparison tests, the organisational structure of the dosimetry service, and the responsibilities within this structure.
