Radiation protection has always included security-related provisions, for example measures to prevent the unauthorised use and illegal transfer of sources, which have contributed to the overall system of radiation safety. In recent years, however, interest in security issues has dramatically increased and the challenge is to ensure that safety and security measures are designed and implemented in an integrated manner so that security measures do not compromise safety and safety measures do not compromise security.

The aim of the workshop is to consider how the implementation of ALARA, in terms of planned and emergency exposure situations, involving worker and public doses, is affected by the introduction of these new security-related measures. In the case of new equipment and procedures, there is also the question of whether exposures arising from security screening devices can be justified.  In addressing these issues, the workshop aims to consider how an optimum balance between protection, safety and security can be achieved.
