17th European ALARA Network workshop on "ALARA in emergency exposure situations"

17thEuropean ALARA Network Workshop [organized in collaboration with NERIS], Lisbon, Portugal, 15 – 17 May 2017

"ALARA in Emergency Exposure Situations "

capture dcran 2016-10-02  16.45.56

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 were:

  • 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.

Programme and participants

The final programme and the list of participants can be accessed here.

As part of the programme, time has been devoted for discussions in working groups between participants. The working groups tackled the following issues:

  1. Can the ALARA principle by fully apply in Emergency Exposure Situations for the members of the public?
  2. Can the ALARA principle be fully apply in Emergency Exposure Situations for the occupationnaly exposed individuals?
  3. (two working groups) 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?

Presentations

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?"

capture dcran 2015-06-08  13.47.39

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.

Working Groups

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 :

  1. Radiography equipment: can we make it safer (WG1)?
  2. Learning from radiography accidents: how do we stop them from happening again (WG2)?
  3. Training and Safety Culture: how can these be improved (WG3)?
  4. The ALARA process in radiography: setting suitable dose and risk constraints (WG4).

Presentations

Session 3 - Learning from Industrial Radiography Incidents

Session 4 - Education and Training and ALARA Culture
