1Hiroshima University.
Summary
The Hiroshima A-bomb experience offers lessons for Japan
Area of Science:
- Psychological impact of mass disasters
- Disaster recovery and reconstruction strategies
- Historical trauma and resilience studies
Context:
- The Eastern Japan Earthquake and Tsunami catastrophe necessitates effective reconstruction and long-term care plans.
- Lessons from the Hiroshima A-bombing provide a framework for understanding and addressing the needs of disaster victims.
- Governmental understanding of citizen and hibakusha daily realities is crucial for successful reconstruction.
Purpose:
- To draw parallels between the Hiroshima A-bomb experience and the Eastern Japan Earthquake and Tsunami.
- To highlight the importance of incorporating victim perspectives into disaster recovery plans.
- To analyze the psychological evolution of A-bomb survivors (hibakusha) to inform long-term care strategies.
Summary:
- Reconstruction success hinges on government understanding and integrating the lived experiences of citizens and hibakusha.
- Open and accurate information sharing is vital for disaster, restoration, and reconstruction processes.
- Three key psychological shifts in hibakusha, from despair to hope and from forgetting to remembering, illustrate resilience over 66 years.
Impact:
- Provides valuable insights for the reconstruction of Eastern Japan following the earthquake and tsunami.
- Offers a model for implementing effective middle- to long-range care plans for catastrophe victims.
- Enhances understanding of survivor psychology, aiding in the support and care of those affected by large-scale disasters.

Flashbulb Memory
A flashbulb memory is a highly vivid and detailed memory, often linked to events of significant emotional impact. These memories stand out in contrast to everyday memories due to their clarity and the precision with which they are recalled. The strong emotions associated with the event act as a catalyst, ensuring that specific details, such as one's location, actions, and even peripheral elements, are etched into memory with remarkable accuracy. For example, many people can vividly recall where...
Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
Constant Volume Calorimetry
Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...
Types of Radioactivity
The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...
