17th European ALARA Network workshop on "ALARA in emergency exposure situations"
17th European ALARA Network Workshop [organized in collaboration with NERIS], Lisbon, Portugal, 15 – 17 May 2017
"ALARA in Emergency Exposure Situations "
Aims and objectives
Emergency exposure situations can arise as a result of a nuclear accident, a malicious or terrorist act, or any other unexpected radiological event. It requires a quick response and sustainable countermeasures and remedial actions in order to avoid or reduce adverse short-term and long-term consequences. Radiation exposures can be received by the public, first responders, workers and volunteers engaged in the post-accident recovery.
The ICRP recommendations and European Basic Safety Standards – the bases for national regulations - re-emphasize the principle of optimisation (ALARA) as applying to emergency exposure situations. For the purpose of radiological protection, reference levels for emergency exposure situations should be set. More importantly, it is necessary to establish emergency plans based on an optimum protection strategy, resulting in more good than harm for the exposed people and the affected territories. In that perspective, lessons learnt from the Fukushima accident are of utmost importance.
The objectives of the workshop are:
- To show, in particular from the experience of Fukushima accident, the challenges posed by the optimisation of exposures in emergency and post-accident situations;
- To review the national arrangements for assessing, monitoring and mitigating the radiological consequences of an emergency, especially with regard to applying the ALARA principle to public and occupational exposures;
- To review the arrangements for managing emergency doses to workers
- To review the arrangements for providing ALARA-based training for the different types of stakeholders who would be engaged in the emergency response and long-term recovery actions.
The workshop will consist of presentations (oral and posters) intended to highlight the main issues, and a significant part of the program will be devoted to discussions within working groups. From these discussions, participants will be expected to produce recommendations on ALARA in emergency exposure situations, which are addressed to relevant local, national and international stakeholders.
Technical exhibits are very welcome!
As part of the programme, time has been devoted for discussions between participants (divided in 4 working groups). The working groups have tackled issues such as :
- Can the ALARA principle by fully apply in Emergency Exposure Situation for the members of the public?
- Can the ALARA principle be fully apply in Emergency Exposure Situation for the occupationnaly exposed individuals?
- Predict the unpredictable. How to ensure emergency plans are optimal from a radiation protection point of view? How to act if the situation goes beyond prediction?
- Are new technologies (modelisation, robot etc.) an asset or a gadget for ALARA?
Note that NERIS will organise its 3rd Workshop just after (17-19 May) at the same location.
Both workshops will be held at IST campus, located at Bobadela, 13 km north of Lisbon.

16th EAN Workshop on "ALARA in Industrial Radiography"
16th European ALARA Network Workshop, Berne, Switzerland, 14 – 16 March 2016
"ALARA in Industrial Radiography - How can it be improved?"
Aims and objectives
Industrial radiography (for non-destructive testing (NDT)) using gamma and X-ray sources is a long-established and widespread practice. A key radiation protection principle is optimisation, to ensure that the radiation exposure of radiography workers and other persons is As Low As Reasonably Achievable (ALARA). In 2001, in Rome, the 5th EAN Workshop specifically considered ALARA in industrial radiography. It was concluded that ALARA was not always being achieved, and improvements in radiography equipment, working procedures, training and safety culture were recommended. Since then, industrial radiography has remained an area of concern in radiation protection, due to the levels of radiation exposure received and, in particular, the number and magnitude of accidental exposures. Consequently, EAN has decided to re-visit this topic.
The objectives of the workshop are:
- To review the conclusions and recommendations of the 5th EAN workshop, held in Rome in 2001, and determine whether any real improvements have been made (see link in the right column).
- To ask what else might be done to improve radiation safety in industrial radiography and ensure that exposures are ALARA.
The workshop consisted of presentations (oral and posters) intended to highlight the main issues, and a significant part of the program was devoted to discussions within working groups. From these discussions, participants are expected to produce recommendations on ALARA in industrial radiography, which are addressed to relevant local, national and international stakeholders.
As part of the programme, time has been devoted for discussions between participants (divided in four working groups). The working groups have tackled issues such as :
- Radiography equipment: can we make it safer (WG1)?
- Learning from radiography accidents: how do we stop them from happening again (WG2)?
- Training and Safety Culture: how can these be improved (WG3)?
- The ALARA process in radiography: setting suitable dose and risk constraints (WG4).

How to test the effectiveness of training ? A practical solution
The 15th EAN workshop on "Improving ALARA Culture through Education and Training" was in particular focus on measuring the effectiveness of training.
Following their presentation during the workshop E. Grindrod and J. Stewart from Public Health England propose in this article an "untraditionnal" approach to test knowledge, application and competences of emergency responders at the end of their training event. The article deals with the advantages and disavantages of this approach and looks for areas of future development.

14th EAN Workshop on "ALARA in existing exposure situations"
14th European ALARA Network Workshop, Ireland 4-6 September 2012
"ALARA IN EXISTING EXPOSURE SITUATIONS"
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
Radiation protection of aircraft crew
Between December 2010 and January 2012, EAN performed a survey about radiation protection of aircraft crew. The following questions were sent to the members of the network.
- What are the main requirements?
- What are the means and tools used to assess aircrew's exposure?
- Is there a specific dose criteria defined for aircraft crew?
3. Could you provide data on the number of aircrew exposed, maximum annual level of exposure, average annual level of exposure, etc.?
14 countries answered the request about radiation protection of aircraft crew: Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Lithuania, Slovenia, Sweden, the Netherlands and the UK. There is not a regulation concerning radiation protection requirements for aircraft crew in Norway.

ERPAN (European Radiation Protection Authorities Network) carried out a survey in April 2010 on how dose constraints, as defined in the EU Directive are applied in the non-nuclear energy sector across Europe. The following questions were sent to the participants to the network.
- Does your country use dose constraints in the context of occupational exposures (non-nuclear sector)
- If so what are they called?
- Are occupational dose constraints mentioned in national legislation/regulations?
- If so, please provide a reference to the relevant regulations?
- Please provide (in English) the actual wording used in the regulations?
- For what industries, processes, tasks, types of workers – all workers? the most exposed workers? specific categories of workers? etc. – are dose constraints used?
- How are dose constraints used in practice?
- Why are dose constraints introduced?
- What are the benefits of introducing dose constraints?
- Who sets dose constraint (utilities or authorities)?
- How are dose constraints set e.g. for a set of sources or for individual sources?
- Are dose constraints “misused”, for example implicitly or explicitly as secondary limits (to dose limits)?
- Are dose constraints used as a regulatory instrument?
- Who manages performance against dose constraints and other occupational radiation protection criteria?
- In what context are dose constraints set: for sites (refers to design) or for tasks (refers to operation)?
- How are dose constraints fixed, implemented, and controlled in each of these cases?
- In practice, has enforcing (individual) dose constraints resulted in negative consequences (e.g. higher collective doses, increased costs, etc.)?
- What approaches have proven successful in discussing dose constraints between regulatory authorities and licensees?
- Have you any experience in balancing occupational radiation protection dose constraints with the management of other risks (e.g. industrial, chemical/biological safety issues)?
Answers from 11 countries were received: Belgium, France, Greece, Ireland, Luxembourg, Norway, Slovenia, Spain, Sweden, Switzerland and the UK. The detailed answers can be found in the Appendix 1 of the EGOE (Expert Group on Occupational Exposure of the CRPPH - Committee on Radiation Protection and Public Health) report on dose constraints.

EAN Strategic Plan 2010-2015
For 1.5 years, the EAN Steering Group has worked on a 2010-2015 Strategic Plan for the network. This document describes the expected work of EAN during this period taking into account the future challenges for ALARA in Europe.
RELIR/OTHEA - Lessons learned from radiological incidents
HPA (the UK) and CEPN (France) have launched the RELIR-OTHEA mirror-website. RELIR/OTHEA is provided by a network of French and English radiation protection stakeholders, who have a joint interest in sharing feedback and experience from radiological incidents, in order to improve the protection of persons working with similar radiation sources. More generally, the aim is to encourage good practices (especially the implementation of the ALARA/ALARP principle) within different sectors - medical and veterinary, industrial, research and education sectors, etc.
The incidents reports are anonymous and have been selected on the basis of those which provide interesting and useful lessons, to help others prevent such incidents and/or mitigate the consequences.
