The secondary standards dosimetry laboratories (SSDLs) calibrate instruments used to measure the amount of radiation in different fields. The laboratories are the critical link between primary standards dosimetry laboratories and end users. The IAEA has published international dosimetry codes of practice and other publications that form the basis of the technical procedures needed for measurements and calibrations. Qualified staff with specific competencies are needed so these procedures are implemented consistently across SSDLs.
The IAEA and World Health Organization (WHO) coordinate the IAEA/WHO Network of Secondary Standards Dosimetry Laboratories. Many SSDLs in the Network were established or upgraded as part of an IAEA Technical Cooperation Project. The IAEA designs and coordinates training courses for technical staff, prepares publications and e-learning material and organizes symposia in the field of dosimetry.
A shortage of adequately trained staff is a serious obstacle to the appropriate operation of an SSDL and its recognition. There is no standardized definition of or education framework for the role of radiation metrologists, who carry out technical work in SSDLs. As a result, the competencies in SSDLs can vary significantly. The SSDL Scientific Committee, which advises the Network Secretariat, suggested drafting a publication on the education of radiation metrologists.
The aim of this publication is to provide information to authorities and stakeholders responsible for or interested in SSDLs on the training and competencies needed for personnel working at an SSDL. It also provides a framework for the education, practical training and competencies of radiation metrologists responsible for SSDL activities, which can be used to harmonize the education of radiation metrologists. A model is included to identify potential gaps and define a professional development plan to cover the necessary competencies of the role of radiation metrologists. This publication may also be useful for other radiation physics laboratories.
The IAEA officers responsible for this publication were P. Toroi and Z. Msimang of the Division of Human Health.
