 One of the main messages is to recognise the importanceof the co-expertise process during recovery
 This means the best approach is working with the affected
people and not for themLessons from Nuclear Accidents
 What have radiological protection
and other professionals learnt?
 The human and ethical dimensions ofnuclear accidents leave a legacy that canhelp support those who may be affectedin the future These dimensions are at least as

significant as the effects of radiation

Lessons from Nuclear Accidents
 What have radiological protection
and other professionals learnt?
 Encourage self-help protection ofaffected communities
 Develop a practical radiologicalprotection cultureOngoing Issues for Fukushima Managing waste fromdecontamination process Release of radioactive water(tritium) into ocean
 Returning and living in affectedareas of Fukushima

 Health surveillance Organising memory of eventsfor future generations

Going Forward Dialogue and communication
with local populations regarding
past experiences is key
