14th European ALARA Network Workshop, Ireland 4-6 September 2012


The concept of “existing exposure situations” was introduced by ICRP in Publication No. 103 (2007), and is included in the revised European Basic Safety Standards Directive. It is defined as exposure situations that already exist when a decision on control has to be taken, such as those caused by natural background radiation and radioactive residues from past practices or events.  Examples include radon in dwellings and buildings with public access, building materials and management of contaminated areas from past practices and post-accidents. Other situations such as exposure from cosmic rays and NORMs may also be included.

Optimisation is the key radiation protection principle for existing exposure situations, although it is not always clear how to apply this in practice.  Consequently, the aim of the 14th EAN workshop is to focus on how the ALARA principle can be applied to the whole range of existing exposure situations.  The Workshop will consider the wider principles and strategies that might be adopted, as well as the specific methods for implementing ALARA in practice. 

This workshop will consist of presentations intended to highlight the main issues, and a significant part of the programme will be devoted to discussions within working groups.  From these discussions, participants will be expected to produce recommendations on ALARA in existing exposure situations addressed to relevant local, national and international stakeholders.

Working Group Topics

  • ALARA challenges and practicalities at the national and regional levels
  • Considerations in choosing reference levels
  • Economical, technical factors and endpoints of optimisation
  • Societal factors and stakeholders engagement
