  1. ORGANISATION OF THE ENVIRONMENTAL MONITORING: LESSONS LEARNT FROM FUKUSHIMA Mélanie MAITRE, Pascal CROUAIL & Thierry SCHNEIDER TERRITORIES Workshop June 13, 2018

  2. GENERAL INTRODUCTION In post-accident situations, the implementation of the environmental monitoring is essential: • To characterize the radiological situation of the environement • To help people to becomeactorsof theirownradiological protection Feedbacks fromChernobyl: bothinstitutional and non institutionalactors come intoplay And in Japan? What are the lessonslearntfrom Fukushima?

  3. OVERALL OBJECTIVE OF THE STUDY Identify the environmental monitoring strategy implemented in Japan following the Fukushima accident Document reviews, analysis of public environmental data bases, etc Highlighting local initiatives developed within the affected territories Interviews of both institutional and local actors involved in the environmental monitoring

  4. The official environmental monitoring set up in Japan

  5. Comprehensive Radiation Monitoring Plan (CRMP) :a national environmental monitoring programme • SomeGeneralities • Created by the JapaneseGovernement in August 2011 – Steered by the NRA sinceSeptember 2012 • Based on the existing monitoring programme • Objectives • Characterise the radiological situation of the environmentthroughoutJapan • Gradual intensification of monitoring (mesh, frequency, etc.) at 250 km to 20 km from the Fukushima power plant

  6. Comprehensive Radiation Monitoring Plan (CRMP) :variousactorsinvolved… On-line publication of the results On-line publication of the results On-line publication of the results NRA CRMP transmission of results

  7. Comprehensive Radiation Monitoring Plan (CRMP) :dissemination of variousresults… Tables of raw data Interactive maps Integrated maps

  8. Local initiatives to measurethe environmentalquality

  9. A multiplication of local initiatives • Mistrusttowardsauthorities, official institutions • Various local initiatives implementedsince 2011… • By municipalities and local communities: • Coordination of additionalstudies to check the results of the official environmental monitoring • Provision of monitoring devices to local populations, with support of RP experts Contamination map – Suetsugi village • By NGOS, citizen networks: • Campaigns to characterize the radiological situation of theirownterritory • Proposingpaidmeasurements of environmentalsamples, WBC, etc. Website NGO « Sokutei Minamisoma » Journal of NGO « Asamigawa Yume Kaigi »

  10. Someexamples of local initiatives (1/3) • To measure the radiological situation of theirenvironement – Exemple of the citizen network SAFECAST https://blog.safecast.org/

  11. Someexamples of local initiatives (2/3) • To measuretheirownexternalexposure – Exemple of the D-Shuttlepersonaldosimeter • Develop by Japanese experts from AIST. • To support local populations (schools, local communities, etc) with help and councellingfrom experts Estimates using the government dose estimation model Source: W. Naito et al., (2017) Individual external dose [mSv] - 1 April 2017

  13. Conclusion

  14. Main lessonslearnt • A national plan (CRMP) bringingtogethermanyactors • Various public platformswithheterogeneous data ➝ Confusion for the users • Various local intiatives in parallel • Resultswhich have all the confidence of local populations • A real opportunity to regain control of theirdaily life • A multiplication of measurements and actors… • Environmental monitoring whichseemsredundant • Lack of sharing and analysisbetween local or even local and national intiatives  Map made by the citizen network SAFECAST  Map made by the Fukushima prefecture thanks to the Gamma-Ray Survey KURAMA II

  15. Remaining issue… • Role of the RP experts… • How to help local population to legitimatetheir actions? • How to coordinateinstitutional and non institutional initiatives to a commonapproach? • Be aware and respect ethical values: • Ensure the autonomy of people – Stakeholder participation and empowerment • How to serve some local communities or the entire population withlimitedmeans • Try to promote a sustainable vigilance • …
