The quality of a dosimetry service provider depends both on the characteristics of the approved dosimetry system[1] (having been type tested) and on the training and experience of the personnel, as well as the procedures calibration and quality assurance programs. This document specifies the criteria and test procedures to be used for periodic verification of the performance of dosimetry services providing personal dosimeters and/or area dosimeters. An area dosimeter can for example be a workstation dosimeter or an environmental dosimeter. Performance evaluation can either be part of the approval procedure for a dosimetry system or consist of an independent check to ensure that a dosimetry service meets the performance requirements linked to a type test. , specified in a national or international standard, under representative exposure conditions which correspond to those expected or simulate the workstation fields of radiological activities subject to dosimetric monitoring. This document applies to personal dosimeters and area dosimeters used for the estimation of the following radiation: external photon radiation with an average energy (fluence-weighted) between 8 keV and 10 MeV, beta radiation of average (fluence-weighted) energy between 60 keV and 1.2 MeV and neutron radiation with an average (fluence-weighted) energy between 25.3 meV (i.e. thermal neutrons exhibiting a Maxwellian energy distribution with kT = 25.3 meV) and 200 MeV. It covers all types of individual or area dosimeters requiring laboratory processing (e.g. thermoluminescent, optically stimulated luminescence, radiophotoluminescent, trace or photographic film detectors) used to make continuous or repeated measurements at regular intervals ( for example, several weeks or a month). Active dosimeters (for dose measurement) can also be treated according to this document. In this case, they should be considered as passive dosimeters (i.e. the dosimetry service records the displayed values and communicates them to the assessment body). [1] If this document were to be applied to a dosimetry system which has not received any approval (test sequence or type test), then, in the remainder of the text, the approval or test should be type are understood to be the technical data sheet established by the manufacturer or required by regulatory authorities.
