Duck and Inform: A Content Analysis of Nuclear Risk Instructional Campaigns

Journal of Contingencies and Crisis Management, Journal Year: 2025, Volume and Issue: 33(2)

Published: April 29, 2025

ABSTRACT In response to the global energy and climate crises, many countries have decided invest in construction of new nuclear power plants. However, these developments bring safety security concerns, further exacerbated by complex relationship between demands escalating geopolitical tensions. Lessons from past emergencies (e.g., Fukushima Zaporizhzhia) highlighted need for preparedness strategies protect public potential incidents, with an emphasis on awareness effective instructional risk communication. This paper presents a content analysis examining themes components within campaigns, assessing their evidence‐based foundations. Specifically, this identifies key elements that should be included enhance effectiveness communications, focusing like IDEA model audience segmentation, both which are recognized as communication methods. A total 47 campaigns 28 different were analysed. The results show while most include crucial instructions, they often fall short fostering internalization public, essential factor ensuring learning achieve behavioural outcomes individuals dealing risks. Moreover, inconsistencies terminology event phase specifications found, could affect clarity comprehension. Given segmentation models communication, recommends integrating into future campaigns. Ultimately, findings provide valuable insights help governmental nongovernmental organizations design develop efforts critical area.

Examples of practical activities related to public understanding of radiation risk following the Fukushima nuclear accident

Radioprotection, Journal Year: 2020, Volume and Issue: 55(4), P. 297 - 307

Published: Oct. 1, 2020

After the Fukushima nuclear accident in Japan, a number of practical activities related to public understanding (PU) radiation risks were implemented inside and outside Prefecture. The various noteworthy approaches strategies behind those have not been organized made explicit thus far. In this study, we PU following accident, discussed them mainly from standpoints communication approaches. As several examples demonstrate, efforts contextualize localize risk forms observed during post-accident recovery Fukushima, these confirmed, through actual experiences, be an important component effective risks. Community-based or citizen science approaches, such as having affected residents citizens measure radioactivity, contributed radiological situations, but some challenges, ethical aspects handling uncertainty, also revealed. era information communications technology, citizens, experts, agencies social media popular platform for disseminating messages demonstrated that can play role providing information. knowledge lessons learned study useful enhancing only other stressors toxic chemicals, preparing future disasters supporting plans periods after disasters.

Risk trade-off analysis of returning home and radiation exposure after a nuclear disaster using a happy life expectancy indicator

Journal of Radiation Research, Journal Year: 2020, Volume and Issue: 62(Supplement_1), P. i101 - i106

Published: Nov. 16, 2020

It is crucial to evaluate ethical issues regarding evacuation orders, especially after a nuclear disaster. After the Fukushima accident in 2011, Japanese government ordered affected people evacuate. The orders have now been lifted many areas. A risk trade-off analysis between benefits and associated with returning home would help evaluating justification for lifting of order aftermath Here, we performed among an increase emotional happiness (positive effect) loss life expectancy due additional radiation exposure (negative effect), using happy (HpLE) indicator. Emotional was estimated questionnaires distributed who lived municipalities where were lifted. Loss under scenario that returnees received 20 mSv year return subsequent exposure. Increase ~1-2 magnitude higher women aged 20, 40 65 years than This finding has implications orders.
