Wet deposition modeling and behavior analysis of 137Cs aerosols using ten observation-based continuous size distributions following the Fukushima accident

Key Points

• Aerosols showed significant behavior variations post-Fukushima, impacting environmental safety.
• Wet deposition rates for 137Cs aerosols peaked shortly after the accident, indicating rapid dispersal.
• Continuous size distribution monitoring provides valuable insights into 137Cs aerosol dynamics.
• Findings highlight the need for improved predictive models in environmental contamination assessments.
