Introduction
Previous EAN Workshops have focused on the optimisation principle in specific circumstances, for example for a specific work sector or particular types of exposure. The subjects have been chosen to reflect areas with potential for the further development and implementation of the concept of ALARA. 

This was the 10-year anniversary of the EAN Workshops, and the aim was to consider the optimisation principle as a whole. This principle is fundamental to radiation protection, and the Workshop aimed to draw together key stakeholders to discuss its past, present and future status. In particular, the Workshop has considered the practical implementation of ALARA, and how this might be improved in the next 10 years.

Objectives and scope of the Workshop
The main objectives of the 10th EAN Workshop were to:

  • Review the past evolution of the ALARA concept, internationally, within the EU, and nationally, in terms of the practical impact on radiation protection;
  • Examine the current status of the implementation of the ALARA principle; and
  • Identify needs for future developments in the concept and implementation of optimisation.

As with previous Workshops, the 10th Workshop consisted of presentations (oral and posters) and work in small groups. Presentations were invited on the following subjects:

  • The history of ALARA in Europe;
  • Future ICRP recommendations on optimisation;
  • International (IAEA) actions on optimisation;
  • Identifying needs for future developments in ALARA implementation; and
  • ALARA implementation in different areas:
  • Occupational exposures in general (ESOREX)
  • Nuclear sector
  • Medical/patient exposures
  • Non-destructive testing
  • Exposures from NORM
  • Public exposures.

The working group sessions considered the following issues:

  • How to encourage the involvement of different stakeholders in implementing ALARA;
  • How to further develop ALARA culture (including education and training);
  • How to assess ALARA implementation (including performance indicators); and
  • How ALARA interfaces with the justification principle, and with other types of risk management.
