17thEuropean 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 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:
- Can the ALARA principle by fully apply in Emergency Exposure Situations for the members of the public?
- Can the ALARA principle be fully apply in Emergency Exposure Situations for the occupationnaly exposed individuals?
- (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?
